And so what ? Its about winning and if running a nasty campaign to discourage the other party's base from voting does it, so be it.
Especially if you are the incumbent and the folks may be ambivalent towards your continued time in office. Don't let the public get it in their head that the opponent is an acceptable or desirable alternative.
So Karl Rove is right that the Obama campaign was all about suppressing enthusiasm for Mitt Romney, knowing there were a lot of people out there not willing to vote for the President.
Karl acts like team Obama did something wrong...They didn't...They played hard ball and won. Mitt Romney ended up a better candidate than many thought, but the seeds of his demise were planted last spring and summer just like they were for one local candidate.
