I think the next ones to drop out will be Governor Rick Perry and Governor Jon Hunstman. Both are polling at the bottom in SC. Hunstman has faired better than Perry, because of NH, but he put all is his eggs in one basket there. It's not going to carry over in SC or elsewhere. Both will get out soon, maybe followed by either santorum and/or newt. Paul will probably stay in the longest and my even run as third party candidate.
