I find it hard to believe Bachmann and Santorum don’t benefit from Cain’s departure.

It's not hard to believe at all when you stop and think about it. Bachmann and Santorum have managed to alienate all the previous supporters of Perry and Cain by their petty attacks on them when they were soaring in the polls.

Gingrich was the only one on stage being nice to everyone, and thus has reaped the benefit.
