The 2024 United States presidential election in Colorado took place on Tuesday, November 5, 2024, as part of the 2024 United States presidential election in which all 50 states plus the District of Columbia participated. Colorado voters chose electors to represent them in the Electoral College via a popular vote. The state of Colorado has 10 electoral votes in the Electoral College, following reapportionment due to the 2020 United States census in which the state gained a seat.
Notably, Colorado saw a significant shift rightward, but less important than other blue states, Republicans did nonetheless flip one seat in Colorado's congressional delegation. Harris won by 6.5%, 7% down from Biden in 2020, and slightly better than Hillary Clinton's margin of 4.9% in 2016, and exceeding Barack Obama's margin 2012. This is the first election since 1996 that Colorado backed the loser of both the electoral vote and the overall popular vote.

### 14th Amendment lawsuit

The Citizens for Responsibility and Ethics in Washington, a left-leaning non-profit, filed a lawsuit on behalf of four Republicans and independent voters, saying that Donald Trump is ineligible to run for president because of a section in the 14th Amendment that states "no person shall ... hold any office, civil or military, under the United States ... who, having previously taken an oath .... as an officer of the United States ... shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof". A trial on this case took place during October and November 2023. The judge found that Trump engaged in insurrection but declined to remove Trump from the primary ballot, saying there is "scant direct evidence regarding whether the Presidency is one of the positions subject to disqualification". On December 19, 2023, the Colorado Supreme Court ruled that Trump is disqualified from the Presidency under Section 3 of the 14th Amendment and ordered that Trump be removed from the 2024 Colorado Republican presidential primary ballot.
Trump appealed this ruling to the Supreme Court of the United States, and arguments were heard in February. The Colorado decision was stayed pending appeal, and Trump was included on the certified ballot, which began to be mailed to overseas voters on January 20. On March 4, 2024, the Supreme Court issued a ruling unanimously reversing the Colorado Supreme Court decision, ruling that states had no authority to remove Trump from their ballots, and this was instead a power held by Congress.

## Analysis

A fast-growing Mountain West state that was formerly Republican leaning, no Republican has won Colorado by double digits at the presidential level since Ronald Reagan in his 1984 landslide re-election victory. Colorado was consistently competitive at the presidential level from the late 1980s going through the 2010s, including Hillary Clinton narrowly winning the state by 4.9% in 2016. In 2020, Democrat Joe Biden carried the state by 13.5%, becoming the first presidential candidate to win Colorado by a double-digit margin since Reagan. The last Republican to win the Centennial State's electoral votes was George W. Bush in his 2004 re-election victory, which he won by a margin of 4.7%. Since then, the state has shifted to the left and broke substantially for Joe Biden in 2020. Today, Colorado is a blue state, with Democrats winning the state in every presidential election starting in 2008, occupying every statewide office since 2023, and holding comfortable majorities in its state legislature.
Trump flipped Pueblo County, which he had won in 2016 but lost in 2020. Nonetheless, he became the first Republican to win the White House without carrying Chaffee or Garfield Counties since William Howard Taft in 1908. Despite the state and the nation swinging right as a whole, several large Colorado counties defied national trends and shifted left, including the West Denver suburban counties of Jefferson, Broomfield and Douglas. Outside of Denver, other large Front Range counties also shifted left, such as Larimer County, home of the city of Fort Collins and El Paso County, home of Colorado Springs. Harris won the highest percentage of the vote in El Paso County since Lyndon B. Johnson's 1964 victory and was also the first Democratic presidential candidate to lose the county by only single digits since 1964. This is the first time since 2000 that Colorado voted for the popular vote loser, and the first time since 1908 that it voted for a Democrat that lost the popular vote.
Trump also became the first president since Franklin D. Roosevelt in 1940 and 1944 to win multiple elections without carrying Colorado, and the first Republican to do so since William McKinley in 1896 and 1900.
