Newt's Rationale

Newt Gingrich can't let Mitt Romney win the election.

Having launched this fierce attack on Romney, Gingrich now must do everything he can to ensure that Romney does ultimately lose. In a re-elected Obama administration, Gingrich can say, "Don't blame me—I warned you that Romney was vulnerable." Maybe fellow-Republicans will agree, maybe they won't, but still he can live to fight another day. But in a Romney administration? Ouch. James Carville will have better access.

So Newt's path is clear. The question is: why do any GOP donors want to join this path? Answer: I doubt they do. Which is why I suspect that the much ballyhooed $5 million check from Sheldon Adelson to Gingrich's Super-PAC may soon be lost in the mail.
