A new Quinnipiac poll in Pennsylvania (April 9-13, 2,103 Dem LV, MoE +/-2.1%) shows no change versus last week. Hillary appears to have stopped Obama's upward momentum, though the write up notes there was no noticeable change in the matchup in the final two days of polling (Saturday and Sunday), conducted just after Obama's comments about small town America exploded onto the scene:

Clinton 50 (nc vs. last poll April 3-6)
Obama 44 (nc)
Undecided 6 (nc)

Overall, Clinton maintains a 6.9% lead in the RCP Average for Pennsylvania.

Other notables from the poll: Nineteen percent (19%) of Obama supporters say they would vote for John McCain in the general election instead of Hillary Clinton, while 26% of Clinton supporters say they would switch to McCain instead of voting for Obama in November.

Clinton's fav/unfav rating remains higher than Obama's. Clinton is viewed favorably by 70% of likely Dem voters in PA and unfavorably by 22%, virtually identical to the 71/23 rating from last week. Obama is viewed favorably by 65% and unfavorably by 20% versus a 67/19 rating last week.

66% view Clinton as trustworthy versus 74% for Obama. 84% say Clinton is a strong leader versus 70% for Obama.
