Thank you! I figured I was being exposed to Obama propaganda.
No place like Free Republic to get the truth.
Rasmussen used to set his party weighting based on his monthly polling of party affiliation. For some unknown reason, he stopped doing this and has arbitrarily weighted it as Dem +3.
Personally, I think that Ras was looking over his shoulder and saw that his numbers would be big outliers compared to the other polls if he went GOP +2... and got scared and went with Dem +3.
