Perry has already bought AIRTIME in South Carolina to attack Romney with prior to the Iowa Caucus. He needs to use it. And use it well.
Perry can attack Romney in Saturday’s debate. Good for him that he is staying in to attack Romney. He currently has the most thriving economy of any State in the Nation and he gets to trash Romney Saturday night and also in South Carolina where he already has the air time for Romney attack ads. Romney started it, now Conservatives get to finish it.
So let him bow out gracefully and run those anti-Myth ads anyway, if he really wants to forward the conservative cause. He's not going to help defeat Romney by sucking votes away from either Santorum or Gingrich in South Carolina.
