also the same reason McCain's wallet and watch would be missing after the fight
Well it would not happen because McCain believes in the 2nd amendment and Obama does not. McCain would draw a weapon first and Obama would be left empty handed.
Thus, no contest.
However, McCain in his prime v. Obama in his prime is no contest. McCain would destroy Obama all days to sunday.
McCain, whether you love or or hate em, is one of the toughest mofos ever for what he went through in his life.
