Trust me, it IS obvious. It was obvious when she hired Rollins, it was obvious when she allowed Rollins to attack Palin, and this just wraps up the story - this one can't be blamed on Rollins, he has left the campaign.
But her supporters don't want to admit it. So they will spin and pretend the 800 pound gorrila isn't sitting on their chests.
Rollins has not left the Bachmann campaign. He has changed roles but if you’d have heard him after the debate, it was obvious he has not left the campaign.
