The new poll of Pennsylvania from Strategic Vision (R) shows a race that has rapidly tightened in the last three weeks, from a landslide Hillary Clinton lead to only a moderately-sized one:

Clinton 49% (-7)
Obama 41% (+3)

The general election match-ups show that Barack Obama still has a lot of ground to make up here, though, should he ultimately win the Democratic nomination:

McCain (R) 47%, Obama (D) 42%
Clinton (D) 47%, McCain (R) 41%

It would hardly be surprising if the Clinton camp doesn't tout this poll in making their case that they remain the more electable option for the Democrats.
