Here's a really interesting article where 11 major polling organizations are studied for their statistical accuracy in the past and ranked accordingly. Not surprisingly, LA Times/Bloomberg (i.e. the one that showed Paul with 1% in Iowa today) and FOX News (i.e. Paul isn't a worthy enough candidate to be included in their next debate) are the crappiest, while SurveyUSA and Rasmussen are the most accurate.

#6 - Zogby. Mr. “John Kerry Will Win” made predictions in 20 states, and in 13 Battleground States. Zogby got 16 calls right, and 4 wrong, and was off by an average of 6.10 points. Two of his final polls were the closest major poll, and another one of his final polls was off by more than 10 points. In the Battleground States, Zogby got 9 right, and 4 wrong, and was off by an average of 4.92 points.
#5 - Mason-Dixon. M-D made predictions in 24 states, and in 13 Battleground States. M-D got 23 calls right, and 1 wrong, and was off by an average of 5.75 points. None of their calls was the closest, but none of their polls was invalidated for being more than 10 points off. In the Battleground States, M-D got 12 right, 1 wrong, and was off by an average of 5.62 points.
#4 - CNN/USA Today/Gallup - CUG made predictions in 15 states, and in 12 Battleground States. CUG got 11 calls right and 4 wrong, and was off by an average of 5.33 points. Two of their final polls was the closest for that state (both in Battleground States), and none of their polls were invalidated for being more than 10 points off. In the Battleground States, CUG got 8 right and 4 wrong, and was off by an average of 5.33 points.
#3 - Research 2000 - R2K made predictions in 13 states, and in 7 Battleground States. R2K got 12 calls right, and 1 wrong, and was off by an average of 5.15 points. One of their final polls was the closest for that state ( in a Battleground State), and none of their polls were invalidated for being more than 10 points off. In the Battleground States, R2K got 6 right and 1 wrong, and was off by an average of 4.57 points.
#2 - A close finish, but number two is Rasmussen Reports. RR made predictions in 33 states, and in 13 Battleground States. RR got all their calls correct, without a single miss, and they were off by an average of 5.82 points. What hurt them was their wide variance of accuracy in support. Three of their final polls were the closest for their state, but another 3 of their final polls were off by more than 10 points. In the Battleground States, RR got all 13 right, and they were off by an average of 4.15 points.
#1 - (drum roll, please) Survey USA. SUSA made predictions in 30 states, and in 9 Battleground States. SUSA got 29 right and 1 wrong, and was off by an average of 3.70 points. So, why does SUSA win with 29/30, and beat RR take second with 33/33? It comes down to hitting the bullseye. EIGHTEEN of Survey USA’s final polls were the closest for that state, almost twice as many as every other major poll PUT TOGETHER! Also, none of their polls were invalidated for being more than 10 points off. In the Battleground States, SUSA got 8 right and 1 wrong, and was off by an average of 3.44 points. Three of SUSA’s final polls in Battleground States were the closest for that state, again the best of any poll.
