Never heard of 'em!
Research 2000 was the third most accurate in state polling in 2004, behind Rasmussen and Survey USA. In 2004, 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.
