Keystone State predictions - Scott Elliott has 'em and he's predicting a comfortable 11% win for Clinton today. I tend to agree: it looks like all the "late deciders" in Pennsylvania are within the "T" between Pittsburgh and Philadelphia. Those older, rural, blue-collar bowlers have been consistent Hillary supporters, even before Obama told them they cling to their guns. That dog won't hunt.

My guess: Clinton - 55% Obama - 45%

This morning's RCP average: Hillary by 6.

Extra - Hillary voter (but not supporter) Bulldog Pundit says 8%; Mark tries 9%. Dr. Taylor says "What? The Pennsylvania primary is finally here?" A similarly exasperated Hedgehog Report notes that Pennsylvanians have been polled thirteen times in the past two weeks.
