The 2008 United States Senate election in Kentucky was held on November 4, 2008. Minority Leader and incumbent Republican U.S. Senator Mitch McConnell won re-election to a fifth term. Although Barack Obama lost Kentucky by a 16.22% margin to John McCain in the concurrent presidential election, McConnell more narrowly kept his seat with a 5.94% margin against businessman Bruce Lunsford. This was a greatly reduced margin from when he won re-election in 2002 with a 29.4% margin.
