Rasmussen and Gallup sauce their polls depending on what they THINK the mood of the public is. Not exactly science. They assumed Barack should get a bump from the economic crisis so they change their dem/rep weighting to reflect that. The problem is that while they did that in their state polls, they now know that their assumptions were false which is why Gallup has McCain/Obama tied among registered voters. The only way for this to happen is for McCain to get a significant advantage the last few days with independents. And I’ll bet that’s exactly what happened.
Zogby is Rush’s Pollster. He correctly predicted the DUI would cause Bush to lose the popular vote to Gore but still win the election.
