McCain Brings in the Attack Dogs

With a key Karl Rove disciple now running the show, expect the McCain campaign to start playing a nastier brand of political hardball shortly. A fairly tepid campaign is about to get a whole lot uglier, a whole lot dirtier and a whole lot more divisive. But can a divisive political strategy win again or are Americans finally sick of such manufactured discord? We'll find out in November but in the meantime, to his credit, Obama still largely appears to be running his own campaign on more positive themes.
