Clark definitely won't be >60% McCain. Obama has a fairly good chance there, IMO. If Obama's large lead continues he may also take Asotin (another county that definitely won't be >60% McCain---this place swings like crazy and I really doubt McCain will do extremely well here even though Bush did), Skamania, and Klickitat.
Spokane would be extremely close under such conditions. Alcon and I both have it going Obama by a fraction of a percent.
Whitman is also hard to predict. It's a likely >40% county, IMO. Whoever wins it will do so by less than 2%. It may be a college county but WSU is fairly conservative as far as big state schools go.
I would also knock Adams down to >60 McCain.
