If she weren't a pro-life Republican who would pop open ANWR's oil reserves like a six pack of Miller Lite, I'd have to think about McCain's VP choice having some effect on my vote.
Oh, and I'm not totally against drilling against ANWR for conservation reasons. I just think it'd be nice to have that oil under our ground in 5-30 years, when the Middle East either can't, or won't, keep selling us their oil. As a hedge, a cushion, an emergency reserve... the "strategic" oil reserve we do have is already being used to manipulate oil prices on occasion.
I don't know much about the conservation arguments against drilling in ANWR, and could easily believe that those arguments can counteract the couple-of-pennies differential it would make in Americans' gas prices. I could also see such arguments falling to the logic of providing fuel for food distribution in a very, very dark future...
I hope not, though.
