Obama is a liberal, and they are obsessed with raising taxes, McCain may flip-flop but he likely won't. McCain supports the war, and Iraq is FAR safer today then 6 years ago, go and ask patraeus. A universal healthcare would very quickly banrapt the U.S. even if it didn't how is he going to get all this money for healthcare for everyone? raise taxes.
I don't think its right that you recieve healthcare if your some government leech not paying taxes and working. Theyre is no such thing as true "bum" anymore, there are tones of halfway homes and such for them to get their lives straight, they just dont want to becuase ther are on drugs or something.
