Howard Dean fired a blank the last time he wrote an op-ed that ran side-by-side with Ken Mehlman.

It looks like he learned a lesson, because Dean's effort this morning in USA Today is much improved. He hits the GOP on Iraq, hits the right angles on the issue of terrorism (bin Laden at large, implementing 9/11 commission recommendations), and also sticks it to Republicans on spending and ethics. All in all, a better and more persuasive effort than last time. The question is whether any undecided voters left out there believe what he says.
