Slate has a survey:

"John McCain's choice of Alaska governor Sarah Palin as his running mate has thrown the political world into a tizzy. With apologies to our long-suffering GOP readers for largely disenfranchising them from yet another poll, let's savor the upside of McCain's decision.        
What's the uppest upside of the Palin choice?

A:Best. Reality. Show. Ever. From the unplanned pregnancy to the "I'm a fucking redneck" boyfriend who "doesn't want kids" to the husband's DUI to the in-law custody scandal, it all makes for trash TV that's irresistibly watchable. (28%)

B: The unilateral disarming by McCain. Contradicting his strongest argument (experience), undermining his strongest claim (judgment) and spotlighting his greatest weakness (age), the maverick thing isn't working out so well lately. Suddenly 72 looks a lot scarier. (56%)

C: The unleashing of the Dogs of Press. New and old media media have joined hands as they do what every fiber of their being tells them to: vet the hell out of the new kid. Stay tuned: more to come. (14%)


Gut call on Palin
Will withdraw ~28%        ~ Will lose the election 58%          Will win the election ~15%
