I agree with the point that Brook made in a previous comment section that, regardless of who takes the presidency, we are getting an upgrade. I believe Obama to have a greater vision for the future, but I can find things to like about McCain.
However, on the VP side, beside the fact that I would disagree with Sarah Palin on a lot -I feel she is out of her element. The very real possibility that McCain would leave her holding the reigns at some point during his term is quite unnerving. Here are videos of Biden and Palin in interviews.
