Republican primary.
Campaign.
Missouri State Representative Allen Icet announced his candidacy in June, 2009. Ambassador Tom Schweich joined the race in July, 2009, after having considered running for US Senator. The primary was a close race. Icet had experience as the chairman of the state house budget committee and he was supported by 95 state legislators. Schweich had experience managing audits and was supported by Lieutenant Governor of Missouri Peter Kinder, former United States Attorney General John Ashcroft, former Governor of Massachusetts Mitt Romney, four Missouri state senators, and two former United States ambassadors.
Schweich criticized Icet for taking trips and meals from lobbyists and for the fact that the state budget rose from $19 billion to $23 billion while Icet was chairman of the house budget committee. Icet defended himself by saying that the trip he accepted was for educational purposes and by saying that most of the budget increases were due to increased federal spending and mandatory increases of things such as Medicare.
In spite of Icet's support from most of the state legislators, Schweich was able to gain a fundraising advantage and bigger name endorsements.

General election.
Campaign.
During the campaign Montee attacked Schweich for not being a Certified Public Accountant. Schweich defended himself by pointing to his experience managing audits. During the debate Schweich argued that the state auditor ought to be more of a law enforcement official; he pointed to the fact that he has law enforcement experience, while Montee did not. Montee argued that the state auditor should be a fiscal expert; she again pointed to the fact that she was a CPA, while Schweich was not.
In the end, Schweich defeated Montee with 50.8% of the vote. Schweich obtained strong leads in the rural parts of the state which was sufficient to overcome Montee's leads in urban St. Louis and Jackson County.
