On the morning of January 22, 2008, Steelman announced that she would seek a second term as State Treasurer, but changed her mind when Governor Matt Blunt announced he would not seek reelection later that same afternoon. Following Blunt's announcement, Steelman announced she would run for Governor.
In the 2008 gubernatorial primary, Steelman ran against Kenny Hulshof, losing to him 187,000 to 173,000. She has been toying for months with challenging Roy Blunt in the Republican primary in 2010 for the U.S. Senate seat to replace retiring Sen. Kit Bond.
