There were times where Quinnipiac had Obama up by 11 in Ohio and Kerry up by a high amount over Bush. It doesn't compare to Gallup, PPP, USA Today, or other traditional polls.
Quinnipiac didn't even poll Ohio until 2006.
Quinnipiac also released their last national poll in 2004 in July.
And the fact that Obama was ahead by 11 in OH at the beginning of October was because of increased Democratic enthusiam, that other polls showed as well. Democrats did really well in early Oct. because that's when their voters tune in to the campaign, then Republicans gain in the final weeks. Other polls showed this increase in D-margin as well in other states.
Besides, only the final polls really matter and usually Quinnipiac polls are accurate.
