McCain isn't my candidate of choice, but I'm thinking he's the only one that can beat Hillary. I can see Hillary winning because I've talked to people that think she's "wonderful."
Remember now this is what was said in 2000 about mccain versus gore and in 1996 about dole versus clinton....
There are plenty of GOP candidates who can win against hillary, its when you nominate a conservative Dem that things get tricky(ie Evan Bayh)
I saw one poll where McCain was leading Hillary Rodham by 52% to 35%.
