Barry Morris Goldwater was a U.S. senator from Arizona from 1953 to 1965 and again from 1969 to 1987. Leading into the hiatus, he made an unsuccessful run for the presidency in 1964, as the candidate of the Republican Party. At the time of his presidential campaign, Goldwater represented the far right wing of his party, and although he did not succeed in becoming president, he reshaped the Republican Party as a conservative institution and laid the foundation for its dominance of presidential politics in the last quarter of the twentieth century and the first decade of the twenty-first.
