I thought last week’s Pew Poll was a complete fraud, and do not trust this one either. They are just trying to get back into the “neigborhood” of the other more respected polls.
I trust Rasmussen Poll the most, but IBD is very good as well.
Gallup is not a very accurate poll, and they are now publishing three different results so they can cover themselves if the election is closer than they thought.
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).
Sadly, that doesn't surprise me but it does make me sick.
