Public Policy Polling tweets that their new national poll (to be released this afternoon) shows Newt Gingrich in the lead, while another polling outfit finds Gingrich and Cain in a statistical tie for the lead in Iowa. So, my predictions have been vindicated. I am going to go out on a limb and predict that this is the end of the flavor-of-the-month process. Rick Santorum will not get a turn, nor will Ron Paul or Gary Johnson. It’s going to be a three-way race between Romney, Cain, and Gingrich. If Cain falters in the face of more revelations of sexual misconduct, it could become a two-way race. Ordinarily, I’d argue the obvious, which is that Romney would rather face two strong conservative candidates than one, but that’s not necessarily the case. Cain and Gingrich have deep flaws but, with both of them in the race, those flaws have to share time. I think they benefit from avoiding the full power of the spotlight, as it shines on both of them. The Not Mitt Romney slice of the electorate is so huge (perhaps as big as 75% in some places) that there may be room for conservatives to split the vote and still beat Romney.
