Heres how I see it. (Note I accidentally forgot Connecticut and I didnt want to make another map, it should be Red though)
Alaska - Parnell, solid
California - This all depends on the candidate. If Feinstein does run, she wins. If the dems cannabalize themselves with crazies, as it looks like, then Whitman wins. If Newsom wins the primary, Whitman wins.
Oregon - If Smith runs, he wins. Kuglonski's never been liked in the state. Maybe Kevin Mannix will make another run.
Idaho - R solid
Nevada - Im assuming that the reason Heller passed on the senate race was in order for him to run for governor. In that case, the job goes to him. If its not him, its probably D.
Utah - R solid
Arizona - Phil Gordon and Terry Goddard will cannabalize themselves in the primary. Both are top tier democrats, and Gordon in particular is known for sleazy mudslinging. The primary will get nasty. Brewer will make it through.
Hawaii - Abercrombie, barely.
Wyoming - solid D
Colorado - Ritter is in deep trouble and he has a lot of good candidates running against him. They are also polling better than him. R
New Mexico - dems hold on to this one, but if anything moves forward on Richardson, then Denish could find herself in trouble
Plains states all the way through Texas - all republican, including Texas (Texas will stick with Perry)
I dont see any partisan movement in Minnesota, Wisconsin, Iowa or Illinois. - all D
Arkansas - Beebe solid D
Tennessee - Bredesen solid D
Alabama - I dont know the players in this one. I think this may be the southern one I get wrong. I defaulted it at R.
Georgia - Barnes, D
Florida - McCollum will win, but not by much, he is a weak candidate, it will just be a really good Republican year
South Carolina - We will have a second Indian-American republican governor in the deep south. Nikki Haley
Michigan - Granholms destruction of the state will hand this one to Republicans
Ohio - Stricklands in trouble, but Kasich will win by only a slim margin
Pennsylvania - DRDRDRDR, we are on the R cycle in how this state elects governors
Maryland - O Malley solid D
New York - Giuliani, by a slim margin R
Connecticut - solid R
Rhode Island - Chafee will win
Vermont - with Douglas leaving, this is the most likely to turn D
New Hamshire & Maine - solid D
This produces a pickup of:
1 ind, 6 republicans
