Obama leads Romney by 6% in Pennsylvania
This poll was apparently leaked, since it won't be officially released until 6:30am Eastern Time Tuesday. I am typing this at 4:46 pm EST, yet this Tweeter has posted the results which apparently have been leaked as of last night:

Also the following National Journal link, dated June 12 on the string, reports on a Obama vs. Romney Quinnipiac poll in PA but the link has been deleted. They probably decided to wait until the official release because they posted it too early.

Quinnipiac has been using LV samples so I assume this is an LV sample especially since a recent poll from another company (Franklin & Marshall College) found Obama up by 12% among RV, which traditionally tilts Democratic relative to LV. http://2012.talkingpointsmemo.com/2012/06/pennsylvania-presidential-election-barack-obama-mitt-romney-poll.php
