There are some bizarre theories out there that Republicans are trying to throw the election because they're happy with Obama. I think that's preposterous for a variety of reasons, not least of which is that Karl Rove's big donors aren't spending over a billion dollars to defeat the President on a lark. Nor is Mitt Romney in the race as a sacrificial lamb. He certainly doesn't need the money.
But if the Romney campaign doesn't achieve some level of competence soon, the voices throwing those sorts of theories around will only get louder.
