I don't see how many of the retreads form 2008 make it, but according to Rasmussen Mike Huckabee is leading the (early) prospective GOP field:
Twenty-nine percent (29%) of Republican voters nationwide say former Arkansas Governor Mike Huckabee is their pick to represent theGOP in the 2012 Presidential campaign. The latest Rasmussen Reports telephone survey finds that 24% prefer former Massachusetts Governor Mitt Romney while 18% would cast their vote for former Alaska Governor Sarah Palin.Former House Speaker Newt Gingrich gets 14% of the vote while Minnesota Governor Tim Pawlenty gets 4%. Six percent (6%) of GOP voters prefer some other candidate while 7% remain undecided.
It appears that some on the far-right are gravitating away from Mrs. Palin (although she has received some love for her new book) and towards Huckabee, Romney appears to be holding pretty strong as the business candidate.
