The 2008 United States Senate special election in Mississippi was held on November 4, 2008. This election was held on the same day of Thad Cochran's re-election bid in the regularly scheduled Class II election. The winner of this special election served the rest of the Senate term, which ended in January 2013. Unlike most Senate elections, this was a non-partisan election in which the candidate who got a majority of the vote won, and if the first-place candidate did not get 50%, a runoff election with the top two candidates would have been held. In the election, no run-off was necessary as Republican nominee and incumbent Republican U.S. Senator Roger Wicker won election to finish the term.

Background

On December 18, 2007, U.S. Senator Trent Lott resigned in his fourth-term to pursue "something else" in the private sector. He ended up starting his own lobbying firm. Mississippi law stated that the Governor of Mississippi had ten days after receiving official notification of the vacancy to appoint an interim senator pending a special election. On December 31, thirteen days after Lott's resignation, Governor Haley Barbour appointed U.S. Representative Roger Wicker on December 31, 2007, 13 days after Lott's resignation.

Scheduling lawsuit

Barbour scheduled the special election for November 4, 2008. Mississippi Attorney General Jim Hood, a member of the Democratic Party, issued a non-binding opinion that the election must be held within one hundred days of Lott's resignation (no later than March 30, 2008), and sued Barbour in Hinds County Circuit Court, arguing that Barbour had 10 days to set a special election within 90 days (no later than March 29, 2008). Hood argued the date of the special election to be March 11, the same day as Mississippi's presidential primary. Governor Barbour claimed that the definition of "year" in the law in question is 365 days. Mississippi Secretary of State Eric Clark, the state's chief elections officer and a fellow Democrat, backed the governor's position. Judge Bobby DeLaughter ruled that the election must take place no later than March 19. On February 6, 2008, after Barbour appealed to the Mississippi Supreme Court, which reversed Judge Delaughter and ruled that the non-partisan special election may be held on November 4.
