Carl Bialik has a nice assessment of the ARG poll in Pennsylvania that includes this tease of the new Quinnipiac numbers due out tomorrow:
Other pollsters’ numbers disagree with ARG’s. Clay Richards, who runs the Quinnipiac University Polling Institute’s Pennsylvania poll, said he doesn’t expect his poll that will be published Tuesday to show much difference from the last one, which had a Clinton lead of six points. “I don’t see that much movement in Pennsylvania myself,” Mr. Richards said by phone from Harrisburg on Monday. He declined to comment specifically on his rival’s contradictory numbers.
