Ron Fournier makes a good point -- Herman Cain's authenticity exposes Mitt Romney's calculation.
That was the bugaboo for Romney four years ago when his policy shifts on abortion, guns, health care and several other issues both failed to endear him to conservatives and undercut inroads he could have made with moderates.
.... Cain is a warning to Romney and the rest of the presidential field, including Barack Obama, that voters will forgive a lot of sins but they can't stand a phony.
So here's my question: Does Herman Cain need Mitt Romney? It's quite possible that he'd lose much of his appeal if Romney weren't the front-runner.
