To help Sen. or House candidates.
And also to force McCain to waste money and time in WV, GA, maybe ND (remember Palin campaigning in Omaha ?), which are still needed in VA, OH, NC, FL, CO, MO, etc, etc.
But, in my prediction map, WV is a toss-up and GA and ND are only lean McCain.
Those states won't flip, especially with McCain coming back slightly in the polls.
They won't flip, sure (except maybe WV which can, especially if Clinton would make a stop, even short, there, just for symbol and MSM noise...),
but McCain cannot afford to be totally absent. And as he is not very rich.....
Plus, McCain has a sort of week bounce and Obama a sort of week-end bounce, so let's see if Gallup and Ras trackings moves really more than just noise.
