GOP Shrinking And Souring?

Andrew Sullivan argues that President Obama isn't the hyper-polarizer that analysis of recent poll results seems to suggest:

The polarization being touted by Rove and Wehner and Gerson and the rest of the Bush left-overs is almost entirely a function of Obama's astonishing popularity among Dems, buoyancy among Independents (whose approval rating is very close to the national average), and extremely polarized and shrinking pool of Republicans. To interpret that as Obama's fault, rather than a function of GOP extremism and disaffection, whipped up by Fox and Drudge and Pajamas and the rest of that machine, is, well, Rovian. But it is a reminder of what alone can keep the Bush-Rove GOP alive: the same old, ancient culture war debate that Obama offers us a chance to move past. They will do all they can to keep dividing this country until they see some signs of progress for their operation. That's all they've got.
