McCain doesn't have much margin for error. If he loses any of the first five, his odds of becoming POTUS are very slim.
The good news is that all of those states are very winnable if he continues running a strong, smart campaign. I'd rather be in McCain's position than Obambi's right now.
Mac is in the same situation as Gore and Kerry faced. Gore invested all his energy into FL. Kerry moved to OH two weeks before the election day in 2004. Mac’s problem is that he has a few more states to worry about.
