I would like to speak for the math-challenged, self-indulgent, and irresponsible wingnuts who wanted Christine O'Donnell to beat Mr. 52-Lifetime-ACU-Rating in the Delaware senatorial primary. I know that geniuses like Mark Murphy and Charles Krauthammer are better than I am at predicting elections. So when the lights of the firmament say O'Donnell is "unelectable," I will accept that premise (for argument's sake). But the story does not end there. Assume the geniuses are right. In fact, assume the worst case: O'Donnell loses the general election and the Senate ends up 50-50, with the tie-breaking vote going to Joe Biden....
