Internal polls are worthless because polls are theoretically supposed to eliminate bias. Why bother with this? I do believe Quinn pulls it out in Nov (given the huge "coming home" effect of Democrats in Cooke), but internal polls are the biggest bunch of nonense. If his internal is showing him down 1 (even by statistica analysis), then I can near guarantee you he's down somewhere around 10 pts right now, which is where other polls are showing the race at as we speak.
What other polls? The only pollster that shows this race as a blowout is WAA.
