Don't you mean NewsTweak?
YEah, Newstewak is good -- I don't trust any of these pollsters really, so for them to give an artificial lead to Bush before the debate and then have it magically vaporize after is not that far out.
However, I seriously doubt they would EVER give Bush an artificial lead. That is just more than a committed lefty could bring herself to do. So, any poll showing the President with a lead I take to be understated, and any poll showing CAIRy with a lead I take to be overstated.
