Hillary or Obama, the fact remains both are extremists. McCain will appeal to the majority and the moderates and Hillary with her hypocrisy and Obama and his disdain for America will cost them the election.
I would like to further point out, I could be completely wrong. America voted for a pot-smoking philanderer over WWII vet with Clinton v. Bush Sr.
They may just vote for Obama the Soap Opera over a Vietnam veteran/hero, simply on account he's "cuter" or "hotter" than McCain.
Sadly, I wish I wasn't being sarcastic.
