Ever watch a boxing match, that IS also one on one, and see the loser make excuses? Granted this was Gore not Obama, but please do not embarrass Obama, like Gore embarrassed himself losing the election to Bush. He is still crying over Florida, that got counted, and recounted, over and over, Bush won far and square.
I think even Obama is man enough to just admit, Romney out debated him in the first debate, and not grovel in excuses, just say Great debate and leave it alone.
As far as getting altitude sickness at 5000 feet, yes that can happen, but it doesn't happen to people like Obama, who you see going up and down stairs like Air Force one, like he was a teenager trotting, and looking cool for the photo op. He is in good shape, 5000 feet would not bother him. Besides Romney wasn't standing in a mile deep hole, with mile long legs, he was at 5000 feet, standing right next to him.
They were 2 boxers in the same ring, AND THE BEST MAN WON! What do they say in the ring? PROTECT YOUSELF AT ALL TIMES!
