The 2008 United States Senate election in Kansas was held on November 4, 2008. Incumbent Republican U.S. Senator Pat Roberts won re-election to a third term.
The state of Kansas has not elected a Democrat to the U.S. Senate since 1932. Kansas's other Republican Senator Sam Brownback announced that he is retiring due to "self-imposed term limits," which meant Roberts became the senior senator from Kansas in 2011. It is considered one of the most Republican states in the U.S. The last time its electors went to a Democrat was the Presidential Election of 1964, when Lyndon Johnson carried the state over Barry Goldwater.
Roberts had announced ahead of the 1996 election that "I plan only to serve two terms in the U.S. Senate",[1] but he broke that pledge in this election.
