Wednesday featured comment
"Gallup showed more favorable results for the GOP than what transpired in 2010 (+12 R on the general ballot iirc, when it actually ended up around +7), so I don't know, I wouldn't say they're biased, but perhaps something is up with their methodology this time. Or maybe they're the only ones that are correct. I don't think anyone would dispute that if Romney is really up by 6 nationally, he's on the road to victory. It's unwise to pick any one poll you like and discount the ones you don't." - y2roby
