1980 Republican Party presidential primaries in the context of "Caucus"

George Herbert Walker Bush (June 12, 1924 – November 30, 2018) was the 41st president of the United States, serving from 1989 to 1993. A member of the Republican Party, he also served as the 43rd vice president under President Ronald Reagan from 1981 to 1989 and previously in various other federal positions.

Born into a wealthy, established family in Milton, Massachusetts, Bush was raised in Greenwich, Connecticut. He attended Phillips Academy and served as a pilot in the United States Navy Reserve during World War II before graduating from Yale and moving to West Texas, where he established oil company Zapata Corporation. Following an unsuccessful run for the United States Senate in 1964, he was elected to represent Texas's 7th congressional district in 1966. President Richard Nixon appointed Bush as the ambassador to the United Nations in 1971 and as chairman of the Republican National Committee in 1973. President Gerald Ford appointed him as the chief of the Liaison Office to the People's Republic of China in 1974 and as the director of central intelligence in 1976. Bush ran for president in 1980 but was defeated in the Republican presidential primaries by Reagan, who then selected Bush as his vice presidential running mate. In the 1988 presidential election, Bush defeated Democrat Michael Dukakis.

Presidential elections were held in the United States on November 4, 1980. In a landslide victory, the Republican ticket of former California governor Ronald Reagan and former director of central intelligence George H. W. Bush defeated the Democratic ticket of incumbent president Jimmy Carter and vice president Walter Mondale and the Independent ticket of Congressman John B. Anderson and former ambassador to Mexico Patrick Lucey. Because of the rise of conservatism after Reagan's victory, many historians consider the election a political realignment.

Carter's unpopularity, his poor relations with Democratic leaders, and the poor economic conditions under his administration encouraged an unsuccessful intra-party challenge from Massachusetts Senator Ted Kennedy. Meanwhile, the Republican primaries were contested between Reagan, former Central Intelligence Agency director George H. W. Bush, Illinois representative John B. Anderson, and several other candidates. All of Reagan's opponents had dropped out by the end of the primaries, and the Republicans nominated a ticket consisting of Reagan and Bush. Anderson entered the general election as an independent candidate with former Wisconsin governor Patrick Lucey as his running mate.
