It's still too early for these polls to mean much, but a new PPP poll finds Huck currently ahead in Iowa - a state he won last cycle:

The key to Huckabee's success is the ability to unite the disparate ideological factions of the Republican Party. 31% of voters think the party's too liberal and with them Huckabee has a 26-21 lead over Gingrich, with Palin a little surprisingly coming in further back at 16%. 48% are comfortable with where the party is ideologically and they go for Huckabee too, by a 33-23 margin over Romney. Huckabee comes in a close second behind Romney with the small group of voters who think the party's too conservative, 27-23.

Another poll, released yesterday, had a similar result.
