The United States presidential election of 1824 was the tenth quadrennial presidential election, held from Tuesday, October 26, to Thursday, December 2, 1824.
 John Quincy Adams was elected President on February 9, 1825.
 The election was the only one in history to be decided by the House of Representatives under the provisions of the Twelfth Amendment to the United States Constitution after no candidate secured a majority of the electoral vote.
 It was also the first U.S. presidential election where the popular vote was recorded, and the only presidential election in which the candidate who received a plurality of electoral votes (Andrew Jackson) did not become President, a source of great bitterness for Jackson and his supporters, who proclaimed the election of Adams a corrupt bargain.
The 2016 Democratic National Convention was a presidential nominating convention, held at the Wells Fargo Center in Philadelphia, Pennsylvania, from July 25 through to July 28, 2016.
 The convention gathered delegates of the Democratic Party, the majority of them elected through a preceding series of primaries and caucuses, to nominate a candidate for president and vice president in the 2016 United States presidential election.
 Former U.S. Secretary of State, Hillary Clinton, was chosen as the party's nominee for president by a 59.67% majority of delegates present at the convention roll call, defeating primary rival Senator Bernie Sanders, who received 39.16% of votes from delegates, and becoming the first female candidate to be formally nominated for presidential by a major political party in the United States.
 Her running mate, Senator Tim Kaine from Virginia, was confirmed by delegates as the party's nominee for vice president by acclamation.
The United States presidential election of 1964 was the 45th quadrennial presidential election.
 It was held on Tuesday, November 3, 1964.
 Democratic candidate and incumbent President Lyndon B. Johnson had come to office less than a year earlier following the assassination of his predecessor John F. Kennedy.
 Johnson, who had successfully associated himself with Kennedy’s popularity, won 61.1% of the popular vote, the highest win by a candidate since James Monroe’s re-election in 1820.
 It was the most lopsided US presidential election in terms of popular votes, and the tenth-most lopsided presidential election in the history of the United States in terms of electoral votes.
 No candidate for president since has equalled or surpassed Johnson’s percentage of the popular vote, and since 1820, only Abraham Lincoln in 1864, Franklin D. Roosevelt in 1936, Richard Nixon in 1972 and Ronald Reagan in 1980 and 1984 have won by a greater electoral vote margin.
The Stop Trump movement, also called the anti-Trump, Dump Trump, or Never Trump movement, was the informal name for the effort on the part of some Republicans and other prominent conservatives to prevent front-runner and now President of the United States Donald Trump from obtaining the Republican Party presidential nomination, and, following his nomination, the presidency, for the 2016 United States presidential election.
 Although Trump's campaign drew a substantial amount of criticism, he was ultimately elected in November 2016 and sworn in as president on January 20, 2017.
Jill Ellen Stein (born May 14, 1950) is an American physician, activist, and politician.
 She was the Green Party's nominee for President of the United States in the 2012 and 2016 elections.
 She was an unsuccessful candidate for governor of Massachusetts in 2002 and 2010.
Following Republican nominee Donald Trump's presumed electoral college victory in the United States presidential election of 2016, a group of computer scientists, cyber security experts, and election monitors raised concerns about the integrity of the election results.
 They urged the campaign staff of Democratic nominee Hillary Clinton, who had conceded the campaign on November 9, to petition for a recount in three key states: Michigan, Pennsylvania, and Wisconsin.
 When the Clinton campaign declined to file for recounts, Green Party presidential nominee Jill Stein agreed to spearhead the recount effort on November 23, on the grounds that unspecified "anomalies" may have affected the election's outcome.
 The Clinton team subsequently pledged to support the recount efforts "in order to ensure the process proceeds in a manner that is fair to all sides."
 President-elect Trump and his supporters filed legal motions in all three states to prevent the recounts.
 Two other states were the subject of recount bids that were separate from Stein's efforts in the Rust Belt states: American Delta Party/Reform Party presidential candidate Rocky De La Fuente filed for a partial recount in Nevada on November 30, and three Florida citizens filed for a complete hand recount in their state on December 6.
The 2016 United States presidential election debates were a series of debates held for the 2016 U.S. presidential general election.
 The Commission on Presidential Debates (CPD), a bipartisan organization formed in 1987, organized three debates among the major presidential candidates.
 The first presidential debate for the 2016 election took place on September 26, 2016, and set the record as the most-watched debate in American history, with 84 million viewers.
 The only vice-presidential debate was held on October 4.
 The second presidential debate took place on October 9, and the final debate took place on October 19.
 All CPD debates occurred from approximately 9 p.m. to 10:30 p.m. EDT (6 p.m. to 7:30 p.m. PDT).
The 2016 New York State Legislature Primary Elections took place on September 13, 2016 and the general election was held on November 8, 2016.
 All 150 members of the New York State Assembly and all 63 seats of the New York State Senate were up for election.
 There are no term limited members as New York does not have term limits for positions at the state level.
 Members of the Assembly and the State Senate serve two year terms.
 The State Senate was heavily contested as the Democrats and Republicans both had 31 seats with the Republicans only controlling the Senate through a coalition deal with Democratic Senator Simcha Felder and the Independent Democratic Conference.
 The 2016 United States presidential election also occurred on the same date as the general election.
Alyson Kennedy (born June 11, 1950) is an American activist, a member of the Socialist Workers Party (SWP) and the party's nominee for President of the United States in the 2016 United States presidential election.
 She was the party's candidate for Vice President in the 2008 United States presidential election.
 The ticket campaigned for young voters especially.
 At the head of the ticket were two different candidates, Roger Calero and James Harris; Harris was an alternate in some states because Calero was Constitutionally ineligible because he is a lawful permanent resident of the United States (holding a green card), and not a US Citizen.
 They were the first pair to qualify for the ballot in Louisiana Calero/Kennedy won 5,127 votes and Harris/Kennedy 2,424.
The Missouri bellwether is a political phenomenon that notes that the state of Missouri voted for the winner in all but three U.S. Presidential election from 1904 to 2016 (the exceptions are 1956, 2008 and 2012).
 While states like Ohio, Iowa, Nevada, and New Mexico have been arguably stronger indicators of political trends in recent years, Missouri was a consistent swing state throughout the 20th century.
 Nevada has voted for the winner of every presidential election from United States presidential election, 1912 to the present, excluding United States presidential election, 1976 and United States presidential election, 2016, perhaps making it the new bellwether state.
 Prior to the 2008 elections, Lincoln County, Missouri was said to be the only bellwether county in a bellwether state.
 Missouri is also considered a bellwether of U.S. views on hot-button social issues such as stem cell research, gay rights, and school vouchers.
 Some economists also consider the state a bellwether for economic trends such as consumer confidence and unemployment.
