Presidential elections were held in the United States on November 2, 2004. Incumbent Republican President George W. Bush and his running mate, incumbent Vice President Dick Cheney, were re-elected to a second term. They narrowly defeated the Democratic ticket of John Kerry, a senator from Massachusetts, and his running mate John Edwards, a senator from North Carolina.
Bush and Cheney were renominated by their party with no difficulty. Meanwhile, the Democrats engaged in a competitive primary. Kerry emerged as the early-front runner but was faced with serious opposition by former Vermont governor Howard Dean, who briefly surged ahead of Kerry in the polls. Kerry won the first set of primaries in January and re-emerged as the front-runner, and Dean dropped out in February. Kerry clinched his party's nomination in March after a series of primary victories over runner-up Edwards, who he ultimately selected to be his running mate.
The September 11 attacks in 2001 decisively reshaped Bush's foreign policy goals and garnered him near-universal support early in his term. However, by 2004 his handling of the war on terror attracted serious debate, particularly over his handling of the 2003 invasion of Iraq. Bush presented himself as a decisive leader and attacked Kerry as a "flip-flopper". Kerry criticized Bush's conduct of the Iraq War, despite having voted for it himself. Domestic issues were debated as well, including the economy and jobs, health care, abortion, same-sex marriage, and embryonic stem cell research.
Bush won by a narrow margin of 35 electoral votes and took 50.7% of the popular vote. Bush swept the South and the Mountain states and took the crucial swing states of Ohio, Iowa, and New Mexico, the last two flipping Republican. Although Kerry flipped New Hampshire, Bush won both more electoral votes and states than in 2000. Ohio was the tipping-point state, and was considered to be the state that allowed Bush to win reelection. Some aspects of the election process were subject to controversy, although not to the degree seen in the 2000 presidential election. Bush won Florida by a 5% margin, a significant improvement over his razor-thin victory margin in the state four years earlier which led to a legal challenge in Bush v. Gore. This remains the most recent presidential election in which the Republican candidate won Colorado, New Mexico, and Virginia.
At the time, Bush received the most popular votes in history, a record which would be broken in 2008. Bush's win was the only Republican popular vote victory during the eight elections from 1992 to 2020. As of 2025, Bush is the only Republican president since 1984 to have won re-election to a consecutive second term.

## Background

George W. Bush won the presidency in 2000 after the U.S. Supreme Court's decision in Bush v. Gore remanded the case to the Florida Supreme Court, which declared there was not sufficient time to hold a recount without violating the U.S. Constitution. Just eight months into his presidency, the terrorist attacks of September 11, 2001, suddenly transformed Bush into a wartime president. Bush's approval ratings surged to near 90%. Within a month, the forces of a coalition led by the United States entered Afghanistan, which had been sheltering Osama bin Laden, suspected mastermind of the September 11 attacks. The Taliban had been removed by December, although a long reconstruction would follow.
The Bush administration then turned its attention to Iraq and argued the need to remove Saddam Hussein from power in Iraq had become urgent. Among the stated reasons were that Saddam's regime had tried to acquire nuclear material and had not properly accounted for biological and chemical material it was known to have previously possessed. Both the possession of these weapons of mass destruction (WMD), and the failure to account for them, would violate the UN sanctions. The assertion about WMD was hotly advanced by the Bush administration from the beginning, but other major powers including China, France, Germany, and Russia remained unconvinced that Iraq was a threat and refused to allow passage of a UN Security Council resolution to authorize the use of force. Iraq permitted UN weapon inspectors in November 2002, who were continuing their work to assess the WMD claim when the Bush administration decided to proceed with war without UN authorization and told the inspectors to leave the country. The United States invaded Iraq on March 20, 2003, along with a "coalition of the willing" that consisted of additional troops from the United Kingdom, and to a lesser extent, from Australia and Poland. Within about three weeks, the invasion caused the collapse of both the Iraqi government and its armed forces; however, the U.S. and allied forces failed to find any weapon of mass destruction in Iraq. Nevertheless, on May 1, Bush landed on the aircraft carrier USS Abraham Lincoln, in a Lockheed S-3 Viking, where he gave a speech announcing the end of "major combat operations" in the Iraq War.

Bush was able to ward off any serious challenge to the Republican nomination. Senator Lincoln Chafee from Rhode Island considered challenging Bush on an anti-war platform in New Hampshire but decided not to run after the capture of Saddam Hussein in December 2003. On March 10, 2004, Bush officially attained the number of delegates needed to be nominated at the 2004 Republican National Convention in New York City. He accepted the nomination on September 2, 2004, and retained Vice President Dick Cheney as his running mate. During the convention and throughout the campaign, Bush focused on two themes: defending America against terrorism and building an ownership society. The ownership society included allowing people to invest some of their Social Security in the stock market, increasing home and stock ownership, and encouraging more people to buy their own health insurance.

#### Democratic primaries

The 2004 Democratic Party presidential primaries took place from January 14 to June 8, 2004, to select the Democratic Party's nominee for president. Before the primaries, Vermont governor Howard Dean was a favorite to win the nomination; however, Massachusetts senator John Kerry won victories in two early races: the Iowa caucuses and the New Hampshire primary. These wins strengthened Kerry's previously weak campaign. By March 11, Kerry had received enough delegates to win the nomination. Other major candidates included North Carolina senator John Edwards and retired U.S. Army general Wesley Clark. Kerry asked Republican senator John McCain to be his running mate but McCain turned down his offer. On July 6, Kerry selected Edwards as his running mate, shortly before the 2004 Democratic National Convention was held later that month in Boston.

#### Democratic National Convention

Heading into the convention, the Kerry–Edwards ticket unveiled its new slogan: a promise to make America "stronger at home and more respected in the world". Kerry made his Vietnam War experience the convention's prominent theme. The keynote address at the convention was delivered by Illinois state senator and U.S. Senate candidate and future president Barack Obama; the speech was well received, and it elevated Obama's status within the Democratic Party.

### Other nominations

There were four other presidential tickets on the ballot in a number of states totaling enough electoral votes to have a theoretical possibility of winning a majority in the Electoral College. They were:
* Michael Badnarik / Richard Campagna, Libertarian Party (campaign). Badnarik was nominated on the third ballot and Campagna on the first ballot at the Libertarian National Convention in Atlanta, Georgia, held May 28–31, 2004.
* David Cobb / Pat LaMarche, Green Party (campaign). Cobb was nominated on the second ballot at the 2004 Green National Convention in Milwaukee, Wisconsin, held June 23–28, 2004.
* Ralph Nader / Peter Camejo, independent (also Reform Party, Independent Party (DE), Populist Party (MD), Better Life Party, Cross-endorsements N.Y., Peace and Justice Party, Independence Parties of New York and South Carolina, and the Vermont Green Party who chose not to ratify the national party's presidential nominee).
* Michael Peroutka / Chuck Baldwin, Constitution Party (also Alaskan Independence Party). Peroutka and Baldwin were unanimously nominated at the Constitution Party National Convention at Valley Forge, Pennsylvania (June 23–26, 2004).

## Issues unique to the election
### Electronic voting machines

Ahead of the 2004 election, some states implemented electronic voting systems. Critics raised several issues about voting machines, particularly those made by Diebold Election Systems. Cybersecurity professionals found security vulnerabilities in Diebold machines. Voting machines made by several companies were also criticized for their lack of a paper trail, which would have made results easier to verify. Democrats also criticized various executives at Diebold, Inc. (the parent company of Diebold Election Systems) for their support of Bush's campaign, stating that it constituted a conflict of interest. Following these issues, California banned the use of Diebold's AccuVote TSX voting machines for elections in 2004.

### Campaign law changes

The 2004 election was the first to be affected by the campaign finance reforms mandated by the Bipartisan Campaign Reform Act of 2002. The act created restrictions on fundraising by political parties and candidates. A large number of independent 527 groups were created to bypass these restrictions. Named for a section of the Internal Revenue Code, these groups were able to raise large amounts of money for various political causes as long as they did not coordinate their activities with political campaigns. Examples of 527s include Swift Boat Veterans for Truth, MoveOn.org, the Media Fund, and America Coming Together. These groups were active throughout the campaign season, spending a record $556 million for all elections in 2004.
The Stand by Your Ad provision of the Bipartisan Campaign Reform Act required political advertisements on television to include a verbal disclaimer identifying the organization or campaign responsible for the advertisement. This provision was intended to force campaigns to take responsibility for negative advertisements. Campaign strategists criticized this requirement, stating that it would waste time and cause voters to be confused.

## General election campaign
### Campaign issues

Bush focused his campaign on national security, presenting himself as a decisive leader and contrasted Kerry as a "flip-flopper." This strategy was designed to convey to American voters the idea that Bush could be trusted to be tough on terrorism while Kerry would be "uncertain in the face of danger." In the final months before the election, Kerry's campaign focused on domestic issues such as the economy and health care. Kerry's campaign managers believed that Kerry had an advantage on domestic issues. Bush's campaign also focused on increasing voter turnout among conservatives. According to one exit poll, people who voted for Bush cited the issues of terrorism and traditional values as the most important factors in their decision. Kerry supporters cited the war in Iraq, the economy and jobs, and health care.

#### Economy

Tax cuts were passed in 2001 and 2003 under the Bush administration with Bush's support. Kerry voted against these tax cuts. During the 2004 campaign, Bush praised these tax cuts, stating that they helped to grow the economy. On the other hand, Kerry attacked Bush for failing to create jobs under his presidency. Kerry stated that he wanted to reduce the United States budget deficit by capping government spending while ending various tax breaks for businesses. Kerry also supported tax credits for businesses that hire additional workers. Bush attacked Kerry for his economic proposals, stating that they would cause Americans to pay higher taxes. Bush also attacked Kerry for previously supporting tax raises, such as a proposed increase on the federal gas tax.

#### Foreign policy

Bush defended the Iraq War, arguing that it was necessary to stop terrorism. He also said that the United States had made progress stopping terrorism in other nations. Bush attacked Kerry for opposing the Iraq War after voting to authorize it in 2002, characterizing the shift as one of many flip-flops by Kerry. Kerry argued that Bush had misled the American public in pursuing the Iraq War, noting that no illegal weapons had been found in Iraq. He said that the Iraq War was a mistake and a diversion from terrorism in other nations such as Afghanistan. After the election, exit polls found that foreign policy concerns were the most important issues for voters.

#### Health care

Health savings accounts (HSAs) were introduced in 2004 as part of the Medicare Prescription Drug, Improvement, and Modernization Act, signed by Bush in December 2003. As part of his 2004 campaign, Bush supported the expansion of HSAs. He proposed tax cuts to help Americans purchase their own health insurance. He also proposed a plan that would allow small businesses to purchase health insurance in large groups. Kerry's health care proposals included government subsidies for businesses that provide health insurance and the expansion of government-run health care programs. Health policy experts stated that Bush's proposals would have a more limited impact than Kerry's proposals. Kerry also attacked Bush for his policy on stem cell research. In 2001, the Bush administration restricted embryonic stem cell research to existing stem cell lines. Kerry stated that this restriction was a barrier to conducting important research.

#### Same-sex marriage

In July 2004, Bush announced his support for a Constitutional amendment to ban same-sex marriage, shortly before the Senate voted on the amendment. Although Kerry stated that he opposed same-sex marriage, he also opposed the amendment, saying that the legality of same-sex marriage should be decided by individual states. The Senate vote failed on July 14.

### Controversies
#### Bush military service controversy

During the campaign, Bush was accused of failing to fulfill his required service in the Texas Air National Guard. A scandal occurred at CBS News after they aired a segment on 60 Minutes Wednesday, introducing what became known as the Killian documents. These documents were allegedly written by Jerry B. Killian, Bush's squadron commander, and they contained various allegations about Bush's service. Serious doubts about the documents' authenticity quickly emerged, leading CBS to appoint a review panel that eventually resulted in the firing of the news producer and other significant staffing changes. The Killian documents were eventually concluded to be forgeries.

#### Kerry military service controversy

Kerry was accused by the Swift Vets and POWs for Truth of distorting his military service in Vietnam. The group challenged the legitimacy of each of the combat medals awarded to Kerry by the U.S. Navy, and the disposition of his discharge. The organization spent $22.4 million in advertisements against Kerry. After the election, political analysts described their advertising campaign as effective. The term swiftboating was used during the campaign to describe the organization's negative advertising, which Democrats saw as unfair. It was also used after the campaign to generally describe a harsh attack by a political opponent that is dishonest, personal and unfair.

### Presidential debates

Three presidential debates and one vice presidential debate were organized by the Commission on Presidential Debates, and held in the autumn of 2004.
Debates among candidates for the 2004 U.S. presidential election :
| No. | Date | Host | City | Moderators | Participants | Viewship (Millions) |
| P1 | Thursday, September 30, 2004 | University of Miami | Coral Gables, Florida | Jim Lehrer | President George W. Bush Senator John Kerry | 62.4 |

* University of Miami Coral Gables, FLCase Western Reserve University Cleveland, OHWashington University in St. Louis St. Louis, MOArizona State University Tempe, AZclass=notpageimage| Sites of the 2004 general election debatesThe first debate was held on September 30, slated to focus on foreign policy. A consensus formed among mainstream pollsters and pundits that Kerry won the debate decisively, strengthening what had come to be seen as a weak and troubled campaign.
* On October 5, the vice presidential debate between Cheney and Edwards. An initial poll by ABC indicated a victory for Cheney, while polls by CNN and MSNBC gave it to Edwards.
* The second presidential debate was conducted in a town meeting format, less formal than the first presidential debate. This debate saw Bush and Kerry taking questions on a variety of subjects from a local audience.
* Bush and Kerry met for the third and final debate on October 13. 51 million viewers watched the debate. After Kerry, responding to a question about gay rights, reminded the audience that Vice President Cheney's daughter was a lesbian, Cheney responded with a statement calling himself "a pretty angry father" due to Kerry using Cheney's daughter's sexual orientation for his political purposes. Polls taken by Gallup in found that Kerry pulled ahead in October, but showed a tight race as the election drew to a close.

### Osama bin Laden videotape

On October 29, four days before the election, excerpts of a video of Osama bin Laden addressing the American people were broadcast on al Jazeera. In his remarks, bin Laden mentions the September 11 attacks, and taunted Bush over his response to them. In the days following the video's release, Bush's lead over Kerry increased by several points.

### Electoral College forecasts

Elections analysts and political pundits issue probabilistic forecasts of the composition of the Electoral College. These forecasts use a variety of factors to estimate the likelihood of each candidate winning the Electoral College electors for that state. Most election predictors use the following ratings:
* "tossup": no advantage
* "tilt" (used by some predictors): advantage that is not quite as strong as "lean"
* "lean" or "leans": slight advantage
* "likely": significant, but surmountable, advantage
* "safe" or "solid": near-certain chance of victory
Below is a list of states considered by one or more forecast to be competitive; states that are deemed to be "safe" or "solid" by forecasters The Cook Political Report, The New York Times, and CNN.

Although Guam has no votes in the Electoral College, it has held a straw poll for its presidential preference since 1980. In 2004, the results were Bush 21,490 (64.1%), Kerry 11,781 (35.1%), Nader 196 (0.58%) and Badnarik 67 (0.2%). Maine and Nebraska each allowed for their electoral votes to be split between candidates. In both states, two electoral votes were awarded to the winner of the statewide race and one electoral vote was awarded to the winner of each congressional district.

### 2004 United States Electoral College

One elector in Minnesota cast a ballot for president with the name of "John Ewards" [sic] written on it. The Electoral College officials certified this ballot as a vote for Edwards for president. The remaining nine electors cast ballots for Kerry. All ten electors in the state cast ballots for Edwards for vice president (Edwards's name was spelled correctly on all ballots for vice president). This was the first time in U.S. history that an elector had cast a vote for the same person to be both president and vice president. Electoral balloting in Minnesota was performed by secret ballot, and none of the electors admitted to casting the Edwards vote for president, so it may never be known who the faithless elector was. It is not even known whether the vote for Edwards was deliberate or unintentional; the Republican Secretary of State and several of the Democratic electors have expressed the opinion that this was an accident.

### Statistical analysis

During the campaign and as the results came in on the night of the election, there was much focus on Ohio, Pennsylvania, and Florida. These three swing states were seen as evenly divided, and with each casting 20 electoral votes or more, they had the power to decide the election. As the final results came in, Kerry took Pennsylvania and then Bush took Florida, focusing all attention on Ohio.
The morning after the election, the winner was still undetermined. The result in Ohio would decide the winner, although the results in New Mexico and Iowa were also undetermined. Bush led in Ohio, but the state was still counting provisional ballots. In the afternoon of the day after the election, Ohio Secretary of State Ken Blackwell announced that there were roughly 135,000 provisional ballots remaining. Kerry's campaign believed that it was statistically impossible to erase Bush's lead. Faced with this announcement, Kerry conceded defeat.
Bush became the first Republican to ever win without carrying New Hampshire, and the first to win the popular vote without Vermont and Illinois. This was the last time a president was re-elected to a consecutive term with a higher share of the electoral vote. Bush carried Colorado despite the state being Kerry's birth state. Bush simultaneously lost his own birth state of Connecticut, making this the only election since 1864 where neither candidate carried their birth state. This election was the first time since 1976 that New Jersey, Connecticut, Vermont, Maine, Illinois, Michigan, and California voted for the losing candidate in the popular vote, as well as the first since 1980 that Maryland did so, and the first since 1948 that Delaware did so. Bush's 2.4% popular vote margin is the smallest ever for a re-elected incumbent president, surpassing the 1812 election.
Bush won three states that have not voted Republican since: Virginia, Colorado, and New Mexico. Virginia had voted Republican in every election from 1968 to 2004 but conversely has voted Democratic in every election since 2008. In contrast, this is the last election in which the losing candidate won any of the following states: Michigan, Pennsylvania, and Wisconsin. This is also the last time a Republican was elected without carrying Maine's 2nd congressional district. This election is the only time in history that every Northeastern state voted Democratic and every former Confederate state voted Republican in the same election. Thus, Bush is the only candidate to win without carrying any Northeastern electoral votes. Furthermore, this was the last election where both major party tickets consisted entirely of white men. This is also the last election where both parties flipped states and is also the most recent year when an incumbent candidate from either party would flip any states, with Bush taking the two which he did not win in 2000, in both New Mexico and Iowa.
Until 2024, this was the last time Nevada voted for the Republican presidential candidate, and the only presidential election since 1988 in which the Republican nominee won the popular vote with a majority, and it remains the only presidential election since 1984 in which the incumbent Republican president won a second consecutive term. Bush also became the only incumbent president to win consecutive re-election after previously losing the popular vote. Bush is the seventh Republican to have won re-election to a consecutive term, along with Abraham Lincoln, Ulysses S. Grant, William McKinley, Dwight D. Eisenhower, Richard Nixon, and Ronald Reagan. The 2004 election had the highest turnout rate among eligible voters since 1968. This is one of only four U.S. presidential elections in which the winner did not carry any of the three Rust Belt states of Michigan, Pennsylvania, and Wisconsin; the others were 2000, 1916 and 1884.
This was the first presidential election since 1988 where a candidate won a majority of the popular vote. This was the last time a Republican candidate won the national popular vote until Donald Trump in 2024. This remains the most recent presidential election in which both major party candidates flipped at least one state. In addition, this was one of only two elections in the 21st century in which a candidate from either party won fewer than 20 states, with the other being 2024, when Kamala Harris also won 19 states. This is the earliest presidential election of which all four of the presidential and vice presidential candidates of both major parties are still alive, and is the most recent to date in which both major party tickets did not include a woman or person of color. This along with the previous election would be the only ones between 1980 and 2024 where the winner won fewer than 300 electoral votes (or below 55% of the electoral college vote).

## Aftermath

This is one of only two U.S. presidential elections, held since the Democrats and Republicans became the two major parties in U.S. politics, in which the winner did not carry any of the three Rust Belt states of Michigan, Pennsylvania, and Wisconsin; the other was 2000, when Bush was first elected.

### Voting problems in Ohio

After the election, activists and election scholars criticized various issues with the election in Ohio. Long lines at polling places over seven hours were reported. An electronic voting machine erroneously gave thousands of extra votes to Bush. Professor Edward B. Foley stated that he believed that Ohio's voting problems did not affect the outcome.

### Objections and conspiracy theories

After the election, many blogs published false rumors claiming to show evidence that voter fraud had prevented Kerry from winning. Although the overall result of the election was not challenged by the Kerry campaign, Green Party presidential candidate David Cobb and Libertarian Party presidential candidate Michael Badnarik obtained a recount in Ohio. This recount was completed December 28, 2004, although on January 24, 2007, a jury convicted two Ohio elections officials of selecting precincts to recount where they already knew the hand total would match the machine total, thereby avoiding having to perform a full recount. Independent candidate Ralph Nader obtained a recount in 11 New Hampshire precincts that used Accuvote voting machines.
At the official counting of the electoral votes on January 6, an objection was made under the Electoral Count Act (now 3 U.S.C. § 15) to Ohio's electoral votes. Because the motion was supported by at least one member of both the House of Representatives and the Senate, the law required that the two houses separate to debate and vote on the objection. In the House of Representatives, the objection was supported by 31 Democrats. It was opposed by 178 Republicans, 88 Democrats and one independent. Not voting were 52 Republicans and 80 Democrats. Four people elected to the House had not yet taken office, and one seat was vacant. In the Senate, it was supported only by its maker, Barbara Boxer, with 74 senators opposed and 25 not voting. During the debate, no Senator argued that the outcome of the election should be changed by either court challenge or revote. Boxer claimed that she had made the motion not to challenge the outcome but "to cast the light of truth on a flawed system which must be fixed now".
Kerry would later state that "the widespread irregularities make it impossible to know for certain that the [Ohio] outcome reflected the will of the voters". In the same article, Democratic National Committee Chairman Howard Dean said: "I'm not confident that the election in Ohio was fairly decided... We know that there was substantial voter suppression, and the machines were not reliable. It should not be a surprise that the Republicans are willing to do things that are unethical to manipulate elections. That's what we suspect has happened."
