when Rick and Newt endorse him, and start saying nice things about him?
We will assume they do. 
He may gain back the few points he lost between now and then. Anything more is hopelessly optimistic thinking coming from Temple Rombot 3000. Obama's attack ads of "populist garbage", to quote someone here, are going to be so successful and make him look worse than Gordon Gekko.
He is not going to lose because of the failure of the conservative vote to show up for him, but rather because of the failure of every moderate to vote for him.
