i think it's a mix of Obama running a great campaign, and the economic backdrop, but most importantly, McCain has ruled himself out of contention cuz of Palin and his own erratic behavior. I am imagining that a lot of people now feel they only have one choice cuz McCain-Palin simply aren't electable.
the correct attack won't be that she's inexperienced, it'll be that McCain was never serious about "ready to lead" the whole time. He thinks Obama has enough experience cuz he chose Palin. So if experience isn't the issue, why is McCain running again?
McCain just gutted the entire logic to his own campaign.
I think it's more than a mix of touchy-feely and policy. I think the right has done a good job at creating emotional logic. That is, an emotional argument that is coherent. It has to all add up to some larger point, or else you could just have an add with puppies and sunsets while an announcer reads off healthcare proposals.
