Duncan Lee Hunter (born May 31, 1948) is an American politician. He has been a Republican member of the House of Representatives from California's 52n congressional district in northern and eastern San Diego since 1981. The district was previously named the 42nd District from 1981 to 1983 and the 45th from 1983 to 1993. Hunter was the chairman of the House Armed Services Committee during the 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 unpromising results in the Nevada Republican caucuses.
