If Kerry picks McCain, he will win Arizona.
If Kerry picks Richardson, he has a chance, but not that much better than with anyone else.
Otherwise, I think Arizona will probably go to Bush. And it will probably be the last time Arizona votes for a Republican presidential candidate for a while.
you still dreaming of a Kerry/McCain ticket?
I honestly think there's as good a chance it will be McCain as there is for any other specific person. I'd say there's around a 20% each for McCain and Edwards. Note that means a 60% chance it won't be one of them...but no one else comes close to 20%.
