From March 19 to June 4, 1912, delegates to the 1912 Republican National Convention were selected through a series of primaries and caucuses to determine the party's nominee for President in the 1912 election. Incumbent President William Howard Taft was chosen over former President Theodore Roosevelt. Taft's victory at the national convention precipitated a fissure in the Republican Party, with Roosevelt standing for the presidency as the candidate of an independent Progressive Party, and the election of Democrat Woodrow Wilson over the divided Republicans.

Theodore Roosevelt Jr., often referred to as Teddy or by his initials, T. R., was an American politician, statesman, soldier, conservationist, naturalist, historian, and writer who served as the 26th president of the United States from 1901 to 1909. He previously served as the 25th vice president under President William McKinley from March to September 1901 and as the 33rd governor of New York from 1899 to 1900. Assuming the presidency after McKinley's assassination, Roosevelt emerged as a leader of the Republican Party and became a driving force for anti-trust and Progressive policies.

As president, Wilson changed the nation's economic policies and led the United States into World War I in 1917. He was the leading architect of the League of Nations, and his progressive stance on foreign policy came to be known as Wilsonianism.

The 1912 United States presidential election was the 32nd quadrennial presidential election, held on Tuesday, November 5, 1912. Democratic Governor Woodrow Wilson unseated incumbent Republican President William Howard Taft and defeated former President Theodore Roosevelt, who ran under the banner of the new Progressive or "Bull Moose" Party. This is the most recent, and the only post-Civil War presidential election in which the second-place candidate was neither a Democrat nor a Republican. This is the most recent election to date in which four candidates received over five percent of the vote.

The 1912 Republican National Convention was held at the Chicago Coliseum, Chicago, Illinois, from June 18 to June 22, 1912. The party nominated President William H. Taft and Vice President James S. Sherman for re-election for the 1912 United States presidential election.

From March 7 to June 6, through a series of primaries and caucuses, voters of the Republican Party elected delegates to the 1916 Republican National Convention, held June 7 to June 10, 1916, in Chicago, Illinois to choose the party's nominee for President of the United States.

The 1916 Republican National Convention was held in Chicago from June 7 to June 10. A major goal of the party's bosses at the convention was to heal the bitter split within the party that had occurred in the 1912 presidential campaign. In that year, Theodore Roosevelt bolted the GOP and formed his own political party, the Progressive Party, which contained most of the GOP's liberals. William Howard Taft, the incumbent president, won the nomination of the regular Republican Party. This split in the GOP ranks divided the Republican vote and led to the election of Democrat Woodrow Wilson.

From March 9 to June 5, 1920, voters of the Republican Party elected delegates to the 1920 Republican National Convention for the purposing of choosing the party's nominee for president in the 1920 election.

A member of the Republican Party, he previously served as a representative and senator from California and was the 36th vice president from 1953 to 1961 under President Dwight D. Eisenhower. His five years in the White House saw reduction of U.S. involvement in the Vietnam War, détente with the Soviet Union and China, the first manned Moon landings, and the establishment of the Environmental Protection Agency and Occupational Safety and Health Administration. Nixon's second term ended early, when he became the only president to resign from office, as a result of the Watergate scandal.

The 1960 United States presidential election was the 44th quadrennial presidential election. It was held on Tuesday, November 8, 1960. In a closely contested election, Democratic United States Senator John F. Kennedy defeated the incumbent vice president Richard Nixon, the Republican nominee. This was the first election in which 50 states participated, and the last in which the District of Columbia did not, marking the first participation of Alaska and Hawaii. This made it the only presidential election where the threshold for victory was 269 electoral votes. It was also the first election in which an incumbent president was ineligible to run for a third term because of the term limits established by the 22nd Amendment.

The 1960 Republican National Convention was held in Chicago, Illinois, from July 25 to July 28, 1960, at the International Amphitheatre. It was the 14th and most recent time overall that Chicago hosted the Republican National Convention, more times than any other city.

Goldwater is the politician most often credited with having sparked the resurgence of the American conservative political movement in the 1960s. Despite his loss of the 1964 U.S. presidential election in a landslide, many political pundits and historians believe he laid the foundation for the conservative revolution to follow, as the grassroots organization and conservative takeover of the Republican Party began a long-term realignment in American politics, which helped to bring about the "Reagan Revolution" of the 1980s. He also had a substantial impact on the American libertarian movement.

The 1964 United States presidential election was the 45th quadrennial presidential election. It was held on Tuesday, November 3, 1964. Incumbent Democratic United States President Lyndon B. Johnson defeated Barry Goldwater, the Republican nominee, in a landslide. With 61.1% of the popular vote, Lyndon B. Johnson won the largest share of the popular vote of any candidate since the largely uncontested 1820 election, in which no candidate of either party has been able to match or surpass.

The 1964 Republican National Convention took place in the Cow Palace, Daly City, California, from July 13 to July 16, 1964. Before 1964, there had been only one national Republican convention on the West Coast, the 1956 Republican National Convention, which also took place in the Cow Palace. Many believed that a convention at San Francisco indicated the rising power of the Republican Party in the west.

From March 12 to June 11, 1968, voters of the Republican Party chose its nominee for president in the 1968 United States presidential election.

The 1972 United States presidential election was the 47th quadrennial presidential election. It was held on Tuesday, November 7, 1972. Incumbent Republican President Richard Nixon handily defeated Democratic Senator George McGovern of South Dakota, receiving all but 18 of 538 electoral votes. Until the 1984 election, this was the largest margin of victory in the Electoral College for a Republican in a U.S. presidential election, and as of 2023 it remains the last time a presidential candidate captured more than 60% of the popular vote. This was also the most recent election in which the entire Midwest was won by a single candidate, particularly because Minnesota has not voted for a Republican for president since. Despite the seismic scope of President Nixon’s victory, heavy ticket-splitting prevented Republicans from making substantial inroads in the parallel Congressional races.

The 1972 Republican National Convention was held from August 21 to August 23, 1972 at the Miami Beach Convention Center in Miami Beach, Florida. It nominated President Richard M. Nixon and Vice President Spiro T. Agnew for reelection. The convention was chaired by House minority leader and future Nixon successor Gerald Ford of Michigan. It was the fifth time that Nixon had been nominated on the Republican ticket for vice president or president. Nixon's five appearances on his party's ticket matched the major-party American standard of Franklin D. Roosevelt, a Democrat who had been nominated for vice president once and president four times.

From August 16 to August 19, 1976, voters of the Republican Party chose its nominee for president in the 1976 United States presidential election.

Kansas is a state in the Midwestern United States. Its capital is Topeka, and its largest city is Wichita. Kansas is a landlocked state bordered by Nebraska to the north; Missouri to the east; Oklahoma to the south; and Colorado to the west. Kansas is named after the Kansas River, which in turn was named after the Kansa Native Americans who lived along its banks. The tribe's name is often said to mean "people of the (south) wind" although this was probably not the term's original meaning.

This is the most recent presidential election, and the first since 1920, in which both major-party candidates for vice-president would go on to become the presidential nominees for their parties in later elections. As of 2023, this is also the earliest presidential election where at least one of the candidates is still living.

Super Tuesday is the United States presidential primary election day in February or March when the greatest number of U.S. states hold primary elections and caucuses. Approximately one-third of all delegates to the presidential nominating conventions can be won on Super Tuesday, more than on any other day.
