What If Huckabee Doesn't Run?

The Fix digs into Palin's and Huckabee's respective numbers:

The base of support for Huckabee and Palin is readily apparent, and for both of them, it starts with born-again evangelicals. The two of them combine for 46 percent of that vote, compared to just 26 percent for Gingrich and Romney. Palin and Huckabee are also the top two vote-getters among women and people without college degrees... It's hard to see Palin having a path to victory that doesn't include Iowa or South Carolina, and both of those early states happened to be Huckabee's strongest in 2008.

I can't help but feel that Huckabee's liberal record, especially on fiscal matters and crime, makes him very unlikely this cycle. How do you run in this climate having pardoned a man who went on to kill police officers?
