The 2010 United States Senate election in Idaho took place on November 2, 2010, alongside 33 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. Incumbent Republican U.S. Senator Mike Crapo won re-election to a third term.
Sullivan, a heavy underdog, criticized Crapo for being in Washington for too long, saying, "Senator Crapo has been in Congress for 18 years. The country is struggling, and I think it's time to make a change." Crapo emphasized his conservative record in Washington.[2]
