McCain's questionable health.

Given the uncertainties of McCain's health status, the nation needs to view Sarah Palin becoming president, or the acting president, a very real possibility.  This is a very frightening possibility given that she is so inexperienced she didn't even know what the "Bush Doctrine" was when asked about it in an interview.  Unfortunately for the ill informed masses, neither do they.  And unfortunately for the voters, Palin was able to bluff her way out of that question.  After a few seconds of looking like a deer staring into the headlights.
