Branstad's influence is such that this could help the Newt-isn't-up-to-it meme spread. In addition, fliers, robocalls and mailers are about to hit Gingrich like ten tons of bricks, mostly from the right. Perry, Bachmann, Santorum and Paul all are gunning to take votes away from Newt. His no-negative-campaign posture might not allow him to withstand what's coming.
