Many folks have accused Rasmussen of leaning Republican, and others PPP leaning Democratic.
Here are 9 races and the current results from PPP vs Rasmussen.
In 12 days we'll get election results and I will come bask to see which is more accurate:
Are these actually the final polls of these states by each poster though, or will they be releasing another one? A couple of years ago, I read a column by Mark Blumenthal about how the polling from different pollsters tends to converge towards the same answer in the final week, even while they diverged wildly throughout the rest of the campaign. Since the final poll is the one that people use to measure "accuracy", it becomes impossible to measure which pollster was actually "right".
Unfortunately, there's no way to check the accuracy of a poll taken a month before the election.
