Steelman Passes On Senate and House Races for 2010

Sarah Steelman says she has "unfinished work" in raising her sons, and will not run for the House or Senate in 2010. "Our youngest, Michael, is 14 and I want to raise him here in Missouri – in the heart of this country, not in Washington D.C.," she wrote.

Which campaign benefits more from the announcement -- Roy Blunt's or Chuck Purgason's?  Blunt is surely glad to know that he won't have a well-funded primary challenger. But does this allow Purgason's call for a return to core Republican principles to be heard more clearly?
