Yet More Pennsylvania Registration Maps

First-Timers	Switchers	Total

My final update on Pennsylvania registration wasn't exactly final. And the late figures show a big boost for Obama. The eight counties most likely to favor Obama—Philadelphia, Allegheny (Pittsburgh), Dauphin (Harrisburg), Centre (State College), and the four suburban counties of Delaware, Montgomery, Bucks, and Chester—account for 65% of the new voters. I've also adjusted the scale a bit, which makes it clearer that the blue shift is concentrated in the Philadelphia media market, Harrisburg, State College, and Erie.
