In 2004, the partisan breakdown in Pennsylvania was 41% Democrat, 39% Republican, 20% independent.
In 2006, it was 43% Democrat, 38% Republican, 19% independent.In 2008, it was 44% Democrat, 37% Republican, 18% independent.And what does PPP predict the partisan makeup of the electorate will be in 2010? 48% Democrat (!), 41% Republican, 11% independent. Color me skeptical that Pennsylvania Democrats will hold a 48% to 41% edge over Republicans in 2010.
