Document 2: United States presidential election in Ohio, 1912: The 1912 United States presidential election in Ohio took place on November 5, 1912. Ohio voters chose 24 electors to the Electoral College, which selected the President and Vice President.
Document 3: United States elections, 1912: The 1912 United States elections elected the members of the 63rd United States Congress, occurring during the Fourth Party System. Amidst a division between incumbent Republican President William Howard Taft and former Republican President Theodore Roosevelt, the Democratic Party won the Presidency and both chambers of Congress, the first time they accomplished that feat since the 1892 election.
Document 4: United States presidential election: The election of President and Vice President of the United States is an indirect election in which citizens of the United States who are registered to vote in one of the 50 U.S. states or Washington, D.C. cast ballots for members of the U.S. Electoral College, known as electors. These electors then in turn cast direct votes, known as electoral votes, for President and Vice President. The candidate who receives an absolute majority of electoral votes for President or Vice President (currently, at least 270 out of a total of 538) is then elected to that office. If no candidate receives an absolute majority for President, the House of Representatives chooses the President; if no one receives a majority for Vice President, then the Senate chooses the Vice President.
Document 5: United States presidential election, 2016: The United States presidential election of 2016 was the 58th quadrennial American presidential election, held on Tuesday, November 8, 2016. In a surprise victory, the Republican ticket of businessman Donald Trump and Indiana Governor Mike Pence defeated the Democratic ticket of former First Lady, U.S. Senator of New York and Secretary of State Hillary Clinton and U.S. Senator from Virginia Tim Kaine.

Concurrent with the presidential election, Senate, House, and many gubernatorial and state and local elections were also held on November 8.
Document 6: United States presidential election, 1912: The United States presidential election of 1912 was the 32nd quadrennial presidential election, held on Tuesday, November 5, 1912. The election was a rare four-way contest. Incumbent President William Howard Taft was renominated by the Republican Party with the support of its conservative wing. After former President Theodore Roosevelt failed to receive the Republican nomination, he called his own convention and created the Progressive Party (nicknamed the “Bull Moose Party”). It nominated Roosevelt and ran candidates for other offices in major states. Democrat Woodrow Wilson was finally nominated on the 46th ballot of a contentious convention, thanks to the support of William Jennings Bryan, the three-time Democratic presidential candidate who still had a large and loyal following in 1912. Meanwhile, the Socialist Party of America renominated its perennial standard-bearer, Eugene V. Debs. It is the last election in which a former, or incumbent, President (Roosevelt) ran for the office without being nominated as either a Democrat or Republican. It is also the last election in which an incumbent president running for re-election (Taft) failed to finish either first or second in the popular vote count.
Document 7: United States presidential election in Iowa, 1912: The 1912 United States presidential election in Iowa took place on November 5, 1912, as part of the 1912 United States presidential election. Iowa voters chose thirteen representatives, or electors, to the Electoral College, who voted for President and Vice President.
Document 8: Democratic Party presidential primaries, 1924: The 1924 Democratic presidential primaries were part of the selection process by which voters of the Democratic Party chose its nominee for President of the United States in the 1924 U.S. presidential election. The concept of a primary election, where any registered party member would vote for a candidate, was relatively new in the American political landscape. In only 12 states were actual primaries held, and even in those the results were not universally binding for the delegates to the Democratic National Convention, where the presidential candidate would be formally chosen. In most of the country, the selection of delegates was confined to state-level conventions and caucuses, under the heavy hand of local political machines. Though William Gibbs McAdoo won a vast majority of states, and much more than half of the popular vote, in those twelve states that held primary elections, it meant little to his performance nationwide. Many of the delegations from states that did "not" hold primary elections favored his main rivals, Oscar Underwood of Alabama and Al Smith of New York, neither of which won any primary elections. As well, the primaries that McAdoo did not win were won by "local sons" who stood no chance of winning the nomination, or in some cases were not even formal candidates. Once at the convention, the party was deadlocked for 102 straight ballots, before dark horse candidate John W. Davis, (who was not a formal candidate when he arrived at the convention) was chosen on the 103rd ballot. Davis went on to lose the election to Republican candidate Calvin Coolidge.
Document 9: United States presidential election, 1920: The United States presidential election of 1920 was the 34th quadrennial presidential election, held on Tuesday, November 2, 1920. The Republicans nominated newspaper publisher and Senator Warren G. Harding from Ohio, while the Democrats chose newspaper publisher and Ohio Governor James M. Cox. Incumbent President Woodrow Wilson, a Democrat, in poor health, chose not to run for a third term. Former President Theodore Roosevelt had been the front-runner for the Republican nomination, but his health collapsed in 1918. He died in January 1919 without leaving an obvious heir to his progressive legacy. With both Wilson and Roosevelt out of the running, the major parties turned to little-known dark horse candidates from the state of Ohio, one of the states with the largest number of electoral votes. As his running mate, Cox chose Franklin D. Roosevelt, a fifth cousin of Theodore Roosevelt who would be elected president himself in 1932.
Document 10: Faithless elector: In United States presidential elections, a faithless elector is a member of the United States Electoral College who does not vote for the presidential or vice-presidential candidate for whom they had pledged to vote. That is, they break faith with the candidate they were pledged to and vote for another candidate, or fail to vote. A pledged elector is only considered a faithless elector by breaking their pledge; unpledged electors have no pledge to break.
Document 11: United States presidential election in Utah, 2012: The 2012 United States presidential election in Utah took place on November 6, 2012 as part of the 2012 General Election in which all 50 states plus The District of Columbia participated. Utah voters chose six electors to represent them in the Electoral College via a popular vote pitting incumbent Democratic President Barack Obama and his running mate, Vice President Joe Biden, against Republican challenger and former Massachusetts Governor Mitt Romney and his running mate, Congressman Paul Ryan. Prior to the election, all 17 news organizations considered this a state Romney would win, or otherwise considered as a safe red state. Utah is among the most heavily Republican states, voting for the Republican ticket in every presidential election since 1968, and is also the only state to have a majority Mormon population, benefiting Romney, the first Mormon to head a major party presidential ticket. He carried every county in the state, all by large margins. However, Obama would go on to win reelection nationwide.
Document 12: Unpledged elector: In United States presidential elections, an unpledged elector is a person nominated to stand as an elector but who has not pledged to support any particular presidential or vice presidential candidate, and is free to vote for any candidate when elected a member of the Electoral College. Presidential elections are indirect, with voters in each state choosing electors on Election Day in November, and these electors choosing the President of the United States and Vice President of the United States in December. Electors today are elected in every state by popular vote, and in practice have since the 19th century almost always agreed in advance to vote for a particular candidate — that is, they are said to have been "pledged" to that candidate. In the 20th century, however, several elections were contested by unpledged electors, who made no pledge to any candidate before the election. These anomalies largely arose over fissures within the Democratic Party over the issues of civil rights and segregation. No serious general election campaign has been mounted to elect unpledged electors in any state since 1964.
Document 13: Electoral College (United States): The United States Electoral College is the mechanism established by the United States Constitution for the indirect election of the President of the United States and Vice President of the United States. Citizens of the United States vote in each state and the District of Columbia at a general election to choose a slate of "electors" pledged to vote for a particular party's candidate.
Document 14: United States presidential election in Ohio, 1984: The 1984 United States presidential election in Ohio took place on November 6, 1984. All 50 states and the District of Columbia, were part of the 1984 United States presidential election. Ohio voters chose 23 electors to the Electoral College, which selected the President and Vice President of the United States.
Document 15: United States presidential election in Ohio, 2012: The 2012 United States presidential election in Ohio took place on November 6, 2012 as part of the 2012 General Election in which all 50 states plus The District of Columbia participated. Ohio voters chose 18 electors to represent them in the Electoral College via a popular vote pitting incumbent Democratic President Barack Obama and his running mate, Vice President Joe Biden, against Republican challenger and former Massachusetts Governor Mitt Romney and his running mate, Congressman Paul Ryan. This continued the streak of having the winner of the overall election winning Ohio as the state has not voted for a losing candidate since Richard Nixon in 1960.
