Goldwater entered Phoenix politics in 1949 when he was elected as a city councilman. He first won a
US Senate seat in
1952, when he upset veteran Democrat and Senate majority leader
Ernest McFarland. He defeated McFarland again in 1958, but would step down from the Senate in 1964 for his presidential campaign. Goldwater had a strong showing in his first reelection in
1958, a year in which the Democrats picked up thirteen seats in the Senate.
Goldwater soon became most associated with labor-union reform and anti-Communism; he was an active supporter of the
Conservative coalition in Congress. However, he rejected the wilder fringes of the
anti-communist movement; in
1956 he sponsored the passage through the Senate of the final version of the
Alaska Mental Health Enabling Act, despite vociferous opposition from opponents who claimed that the Act was a communist plot to establish concentration camps in
Alaska. His work on labor issues led to Congress passing major anti-corruption reforms in 1957, and an all-out campaign by the
AFL-CIO to defeat his 1958 reelection bid. He voted against the censure of Senator
Joseph McCarthy in 1954, but himself was much more prudent than McCarthy and never actually charged any individual with being a Communist/Soviet agent. Goldwater emphasized his strong opposition to the worldwide spread of Communism in his 1960 book
The Conscience of a Conservative. The book became an important reference text in conservative political circles.
Goldwater supported the Arizona
NAACP and was involved in desegregating the Arizona
National Guard. Nationally, he supported the
Civil Rights Acts of 1957 and 1960 and the constitutional amendment banning the poll tax. However, he opposed the much more comprehensive
Civil Rights Act of 1964; he argued that, among other things, it unconstitutionally extended the federal government's commerce power to private citizens in its drive to "legislate morality" and restrict the rights of employers. Since conservative Southern Democrats were the main opponents to the Civil Rights Act of 1964 and previous civil rights legislation, Goldwater's opposition to the 1964 Act, in which he was joined by only four other non-Southern Republican senators, strongly boosted Goldwater's standing among white Southerners who opposed such federal legislation.
In 1964, he fought and won a bitterly contested, multi-candidate race for the
Republican Party's presidential nomination. His main rival was New York Governor
Nelson A. Rockefeller, whom he defeated in the California primary. His nomination was opposed by liberal Republicans who thought Goldwater's hardline foreign policy stances would bring about a deadly confrontation with the
Soviet Union. He would eventually
lose to President Lyndon Johnson by one of the largest margins in the history of U.S. Presidential elections. Consequently, the Republican Party suffered a significant setback nationally, losing many seats in both houses of Congress. Goldwater carried only his home state and five (formerly Democratic) Southern states. Many Republicans at the time angrily turned against Goldwater, claiming that his defeat had significantly set back the party's chances of future national success. (There was a minor controversy over Goldwater's having been born in Arizona when it was not yet a state.)
He remained popular in Arizona, though, and in the
1968 Senate election he was elected again (this time to the seat of Carl Hayden, who was retiring). He was subsequently reelected in 1974 and 1980. The
1974 election saw Goldwater easily reelected. This occurred in a year in which Republicans lost three Senate seats because of the party's unpopularity over the
Watergate scandal.
Goldwater seriously considered retirement in
1980 before deciding to run for reelection. Peggy Goldwater had hoped that her husband's Senate term that was due to end in January 1981 would be his last, as she was looking forward to spending more time with her husband in retirement. However, Goldwater decided to run, planning on making the term his last in the Senate. Goldwater faced a surprisingly tough battle for reelection. First, he was viewed as out of touch for several reasons. One was the fact that because he had planned to retire in 1981, Goldwater had not visited many areas of Arizona outside of Phoenix and Tucson. Second, he was challenged by a particularly tough opponent.
Bill Schulz was a former Republican turned Democrat who was a wealthy
real estate developer. Schulz was able to infuse massive amounts of money into the campaign from his own fortune. And finally, Arizona's changing population hurt Goldwater. The state's population had exploded, with a huge portion of the electorate having not lived in the state when Goldwater was last elected in 1974, and were not familiar with the Senator. Goldwater was on the defensive for much of the campaign. Early returns on election night seemed to indicate that Schulz would win. The counting of votes continued through the night and into the next morning. Around daybreak Goldwater learned that he had been reelected. Goldwater's margin could be traced to his winning a high percentage of
absentee votes, which were among the last to be counted. Goldwater's surprisingly close victory in 1980 is interesting given that Ronald Reagan won the Presidency in a large victory over
Jimmy Carter, and that the Republicans regained control of the Senate, electing twelve new Senators who rode Reagan's
coattails.
Goldwater retired in 1987, serving as chair of the Senate Intelligence and Armed Services Committees in his final term. Despite his reputation as a firebrand in the 1960s, by the end of his career he was considered a stabilizing influence in the Senate, one of the most respected members of either major party. Yet Goldwater remained staunchly anti-Communist and "hawkish" on military issues. He led the unsuccessful fight against ratification of the
Panama Canal Treaty in the 1970s, which returned control of the canal zone to the Republic of
Panama. His most important legislative achievement may have been the
Goldwater-Nichols Act, which reorganized the U.S. military's senior-command structure.
Goldwater was an unwavering supporter of Wisconsin's Republican Senator
Joseph McCarthy to the end (one of only 22 Senators who voted against McCarthy's censure). He was also friends with Senator
John F. Kennedy of Massachusetts; in fact, Goldwater anticipated that a contest for the presidency between John F. Kennedy and Goldwater himself would have been an enjoyable experience, with lively debates between them, one of which was to be held on board a plane in flight. Goldwater was grief-stricken by the
assassination of Kennedy and was greatly disappointed that his opponent in the race would not be JFK, but instead Kennedy's Vice President, the former Senate Majority Leader
Lyndon B. Johnson of Texas. Goldwater disliked Johnson (who he said "used every dirty trick in the bag"), and
Richard M. Nixon of California, whom he later called "the most dishonest individual I have ever met in my life." It is believed Goldwater, then a Senator, forced Nixon to resign at the height of Watergate by threatening to vote in favor of removing him from office if he did not. The term "Goldwater moment" has been used to describe a moment when members of Congress from the President's party disagree and go against the wishes of the President.
His
1984 Cable Franchise Policy and Communications Act allowed local governments to require the transmission of
public access television, also called PEG (Public, Education, and Government) access channels, barred cable operators from exercising editorial control over content of programs carried on PEG channels, and absolved them from liability for their content.
In 2006, his political ideals were revived in the "Jackson Stephens Campaign" in which Republican groups in law schools (namely, the University of Florida) sought to republish widely Goldwater's basic conservative political tenets in graduate school environments.
