Newt's mystifyingly bad debate performance seems to have sealed his fate in the state. But he is still in the lead nationally, and Shelly looks set to keep financing him. Nate Silver has a good guide to what will then be a long month without binding primaries. It's striking that Romney's leads in heavily Mormon Arizona and his home state of Michigan are rather shallow.
Here's the weird thing. I find myself rooting for Gingrich now, one of the most repulsive, nasty and delusional men in American public life. This primary season – when it hasn't eaten deep into my soul – has driven me to all sorts of strange emotions. There were a few nanoseconds when I even wanted Santorum to rally after Iowa. That's a horse race for you, I guess.
