Scott Walker's decision to bow out of the race for governor has raised the stakes for the remaining two candidates.
Some analysts say Walker's decision will change how and when money is spent in what was already shaping up to be an expensive high-stakes battle.
Walker -- a former state Assembly member who became Milwaukee County executive in 2002 -- announced his withdrawal from the race Friday.
That leaves fellow Republican Mark Green unopposed in his bid to unseat Democratic Governor Jim Doyle.
With no September primary, Doyle misses the chance to sit back as the two rivals fight between themselves.
And Green, a four term congressman from Green Bay, is deprived of the name recognition a primary delivers.
But one analyst says Green will benefit from less scrutiny and can now refocus his efforts from party voters to middle-of-the-road voters.
