Conventional wisdom holds that this week's Chris Christie boomlet means the GOP is desperate for a savior. The reality is that, at some point, Republicans will have to start drilling deeper on their own into the candidates they've got.
Put it this way: The GOP nominee is running against the incumbent president. Unlike the incumbent, Herman Cain has at least twice identified the causes of a large failing enterprise, designed goals, achieved them, and by all accounts inspired the people he was supposed to lead. Not least, Mr. Cain's life experience suggests that, unlike the incumbent, he will adjust his ideas to reality.
Herman Cain is a credible candidate. Whether he deserves to be president is something voters will decide. But he deserves a serious look.
