Larison seems to think so:

It seems to me that Huckabee now starts to look much better to the conservative elites who were ridiculing him as Huckleberry just half a year ago; he becomes the relatively safe governing choice who can also generate tremendous grassroots enthusiasm. Many of his former critics may come to recognize the missed opportunity of running with Huckabee’s pseudo-populism on economics this year, and going forward he may be able to develop a policy agenda that is not limited to praising the wonders of the Fair Tax. Not having been a critic of Palin, Huckabee will not have alienated her supporters, and he will probably carefully avoid doing so over the next few years in the same way that he stayed on good terms with McCain voters. Provided that he never, ever again tells the ridiculous story about how foreign wars make it possible for children to have schooldesks, and provided that he could get someone to give him some money, he could become the presumptive frontrunner. Having spoken out against the bailout early on, he will be well-positioned to satisfy libertarians and populists alike. Given the deterioration of the McCain campaign since it went to war with journalists, the value of favorable free media coverage, which Huckabee was able to attract so effectively during the primaries, cannot be underestimated.

I tend to agree with this. For all the hubbub surrounding Sarah Palin, she never really scared me. Huckabee, on the other hand, scared the bejesus out of me, and not just because he’s a bejesus freak — he’s incredibly charismatic and just plain likable, and is very, very good at hiding his bat-shit crazy side.
