Is it too late for Sarah Palin...

...to swoop into Iowa and endorse someone at the last minute? Talk about a game changer!

Ms. Palin could give quite a boost to one of the three cultural conservatives in the race, Rick Perry, Rick Santorum or Michele Bachmann, vaulting one of them into a solid third place finish. Or, dare I say it -- second? -- behind Ron Paul and ahead of Mitt Romney? Remember, this thing is very fluid.

(My guess at this point would be Santorum. He's already moving up in the polls.)
