Rasmussen is okay if you rework his party weighting. If you did know he is very agressively oversampling dems (7 to 8 points).
I like TIPP & Battleground the most. TIPP because they were the most accurate in 2004, their oversample of dems is within historic norms, and they publish their internals. Battleground because the have both a dem and rep pollster doing the poll, they publish internals, and their oversample of dems is within the range of believablity (Dem +5 to +6).
I am surprised Pew stopped polling now when McCain made up 9% in a few days over their last poll. Either they know their last poll was a total fraud, or they want a couple days of no polling to use a “late McCain surge” as an excuse for being wrong.
