“How do you know Gallup is using a “current heavy weighting of Republicans?”
Just asking...”
I don’t know. It is just a guess based on (1) the fact that Gallup is alone in seeing such strong support for Romney, (2) we know from news stories that Gallup has being doing some late-cycle tweaking of its methodology (although admittedly those stories focused on the likelihood that the changes favored Obama), and (3) we know that the Obama folks have put tremendous pressure on Gallup, including the Justice Department’s filing of a lawsuit against Gallup.
