Background: Duncan Lee Hunter (born May 31, 1948) is an American politician. He was a Republican member of the House of Representatives from California's 52nd, 45th and 42nd districts from 1981 to 2009. Hunter was the chairman of the House Armed Services Committee during the 108th and 109th Congress. Hunter sought the Republican Party nomination for President of the United States for 2008, but his campaign failed to attract significant voters or delegates in early primary and caucus states, and he dropped out after the Nevada Republican caucuses.
Context: In 1980, Hunter was recruited to run for Congress in what was then the 42nd District against 18-year incumbent Democrat Lionel Van Deerlin. Hunter was initially an underdog in a district where Democrats outnumbered Republicans by almost 2 to 1. However, his attacks on Van Deerlin's record on national defense gained traction in a district dominated by military bases and personnel. Van Deerlin did not respond quickly enough, and Hunter narrowly defeated him. He was one of many Republicans swept into office from historically Democratic districts as a result of the "Reagan revolution"; Van Deerlin had been the district's only congressman since its creation in 1963. After the 1980 census, many of the more Democratic areas were cut out of Hunter's district, and he was reelected 13 more times with no substantive opposition. His district was renumbered as the 45th District in 1983 and the 52nd in 1993.  In the 2006 general election, he defeated Navy veteran/minister John Rinaldi, a Democrat, and Michael Benoit, a Libertarian. Hunter was re-elected with 65 percent of the vote, a 33-point margin over Rinaldi.  On March 20, 2007, Hunter announced that, as part of his presidential bid, he would not seek re-election to the House of Representatives in 2008. After his son, Duncan D. Hunter, announced his candidacy for his father's seat, the younger Hunter was recalled by the United States Marine Corps to serve in the Operation Enduring Freedom - Afghanistan. During Duncan D. Hunter's active service, his wife, Margaret Hunter, campaigned on his behalf. On June 3, 2008 Duncan D. Hunter won 72% of the Republican Primary vote and became the Republican nominee to replace his father representing the 52nd District.
