Final Push
Here is an interesting analysis that says, assuming the latest polls are correct (and they probably aren't), that McCain just has to pick up about 430,000 disgruntled Hillary voters (the PUMAs) in key states (out of 18,000,000) to win the electoral college handily, or less than 2.5%!
Less than 200,000 would flip Pennsylvania, for example.
Certainly seems within the realm of possibility.
Make it a reality!
