The 2010 United States Senate election in Missouri took place on November 2, 2010, alongside 36 other elections to the United States Senate in other states, as well as elections to the United States House of Representatives and various state and local elections. Primary elections were held on August 3, 2010. Incumbent Republican U.S. Senator Kit Bond decided to retire instead of seeking a fifth term. Republican nominee Roy Blunt won the open seat.
Carnahan and national Democrats heavily criticized Blunt for his support of bailouts, calling him "Bailout Blunt." Blunt criticized her for supporting President Obama's stimulus package, the cap-and-trade energy bill, and the Affordable Care Act.
Carnahan was endorsed by the Kansas City Star, St. Louis Post-Dispatch, and St. Louis American.
Blunt was endorsed by the Quincy Herald-Whig and St. Joseph News-Press.
