McCain will win hands down

Mr. McCain will be helped if he uses Mr. Obama's actions to paint his opponent as someone driven by an all-powerful instinct to look out only for himself. In a contest over who is willing to put principle above personal ambition and self-interest, John McCain, a war hero and a former POW, wins hands down. That may not be the most important issue to voters in electing a president, but it's something they will rightly take into account.
