The Huckabee Fade

Henry Payne reports:

Michigan pollster Steve Mitchell of Mitchell Research is running tracking polls starting today and has McCain up six points over Romney with Paul/Rudy/Huckabee in a distant tie for third.

Okay, so maybe Michigan isn't such favorable ground for Huckabee after all. (Too many Catholics, perhaps?) And if he fades to a "distant" third, I really don't see how he rebounds to win South Carolina. What's less clear, though, is whether a Huck fade helps Romney or McCain ...

Update: On the other hand, we have this.
