Public Policy Polling a Democratic firm is once again embroiled in controversy. They put out a poll this morning that has a larger Democratic electorate and a smaller Republican electorate than in 2008, the best year Democrats have had since the 80's. No one thinks they'll have a year like that in 2012 and that the electorate may be closer to 2010 than 2008.
No one in this debate understands why PPP's polls before elections are good and their polls prior to that are very Democratic. It's the pattern they went through in 2009-2010 when their polls were also very Democratic. They switched to a likely voter model from a registered voter model, around Labor Day 2010. Suddenly their electorates had a lot more Republicans and less Democrats. The numbers changed dramatically. Their likely voter model was strong. Their registered voter model is from Mars. I'm sure they'll switch again around Labor Day 2012 and then crow about how close they were, hoping we'll once again forget how inaccurate their polls were before then.
