You know you you are, and you know why you're here, so let me spell out the other side for the sake of balance:
Suppose McCain/Palin wins the election, but the Senator from Arizona is Unavailable before December 15, the date of the formal election of the President via the Electoral College ballots. Republican electors have two options: to honor the spirit of the Constitution's Article II and the 20th Amendment and vote Gov. Palin as President-Elect; or to select a candidate of their own choosing, perhaps at the behest of the Republican National Committee. YOUR worst-case scenario, worse than Newt, worse than Cheney, even worse than Huckabee: Tom Delay is elected President. Remember: he's not a convicted felon, and it's looking a lot like all the charges will end up being dismissed in the end anyway.
