Ernest Gruening, whom Gravel had defeated twelve years prior in an election for the same seat. Gruening later went on to lose the general election to Republican nominee Frank Murkowski, a banker. After the loss of Gravel's seat, no Alaska Democrat would win a congressional race again until Mark Begich's narrow, protracted triumph in Alaska's 2008 Senate election. First elected in 1968, by 1980 two-term Democratic incumbent Mike Gravel had become noted for a filibuster that attempted to end the draft during the Vietnam War and for including the full text of the Pentagon Papers in the Congressional Record. Gravel faced a challenging bid for re-election, complicated by the fact that his triumph over Ernest Gruening years prior had made him a pariah in the Alaska Democratic Party. Though Gravel had campaigned to be selected as George McGovern's running mate in the 1972 U.S. presidential election and had easily won re-election to the Senate in 1974, he had never established a strong political base in Alaska. The passage of a controversial land bill earlier in the year, as opposed to a compromise bill worked out by fellow senator Ted Stevens that failed thanks to Gravel two years prior, further harmed his re-election bid. A group of Democrats, including future governor Steve Cowper, campaigned against Gravel on the land bill issue. The sources of Gravel's campaign funds, some of which came from political action committees outside the state, also became an issue in the contest. Another factor may have been Alaska's blanket primary system, which allows unlimited cross-over voting across parties and from its large unaffiliated electorate; Republicans believed Gruening would be an easier candidate to defeat in the general election. The blanket primary had first been used in the 1968 election, and was something Gravel himself was able to capitalize upon in his 1968 campaign. Gravel would later comment that by the time of his primary defeat, he had alienated "almost every constituency in Alaska." In the August 26, 1980, primary Gruening defeated Gravel by 11 percentage points. Arizona Incumbent Republican Barry Goldwater decided to run for reelection to a third consecutive term, after returning to the U.S. Senate in 1968 following his failed Presidential run in 1964 against Lyndon B. Johnson. Goldwater defeated Democratic Party nominee Bill Schulz in the general election, but only by a narrow margin, which later caused Goldwater to decide against running for reelection to
