What If Huckabee Doesn't Run?

Allahpundit wonders:

Palin’s the big winner. She takes 34 percent of [Mike Huckabee's] supporters as a second choice compared to just 19 percent for Gingrich and 17 percent for Romney. That’s a considerable spread, to the point where I wonder if there aren’t some establishment anti-Palin Republicans out there suddenly getting very nervous at the thought that Huck might not run and that social conservatives will unite behind Palin. They’re going to need a stalking horse to bleed some of those votes away from her. But who, if not Huck?
