Why is Obama's team running such an inept campaign?

There is a good chance the Obama campaign is about to disintegrate, if only briefly. Obama is about to walk through “the valley of death,” where candidates lose their way and are tested on an arid march. In this familiar story, the campaign that could do no wrong can do no right: Pundits who have predicted an Obama victory reverse course and insist Romney is a sure bet.

Republicans should restrain their exuberance. The race will certainly tighten again if this president fixes a fundamental and possibly fatal political mistake:

Obama is asking America to be a polarized, angry country, where we are at war with each other, tearing at our own throats. Romney is asking us to be a country at peace with itself.

Unless Obama changes course, he will not make it through the valley. This is a race Romney wins.
