McCaskill had earlier defeated incumbent Governor Bob Holden in the Democratic primary. This was the first time a sitting Governor of Missouri had been defeated in a primary and the first time any United States governor had lost in a primary since the 1994 elections.[5]
Coincidentally, McCaskill's mother, Betty Anne, had previously been defeated by Blunt's grandfather, Leroy Blunt, in a 1978 General Assembly election. Blunt's father, Roy Blunt, was a Congressman and served with McCaskill in the U.S. Senate from 2011 to 2019.

The 2004 Washington gubernatorial election was held on November 2, 2004. The race gained national attention for its legal twists and extremely close finish, among the closest political races in United States election history. RepublicanDino Rossi was declared the winner in the initial automated count and again in a subsequent automated recount, but after a second recount done by hand, Democrat Christine Gregoire took the lead by a margin of 129 votes.
Although Gregoire was sworn in as governor of Washington on January 12, 2005, Rossi did not formally concede and called for a re-vote over concerns about the integrity of the election. The Republican Party filed a lawsuit in Chelan County Superior Court contesting the election, but the trial judge ruled against it, citing lack of evidence of deliberate electoral sabotage.[7] Rossi chose not to appeal to the Washington State Supreme Court, formally conceding the election on June 6, 2005.
