In a new Quinnipiac poll in Pennsylvania (March 24-31, 1,549 Dem LV, MoE +/- 2.5%), Clinton's lead over Obama is down to single-digits after leading by 12 a few weeks ago. Still, her lead is not as small as it was in late February, when Obama trailed by just 6 points.

Clinton 50 (-3 vs. last poll, March 10-16)
