What did he say ???
When you look at aggregate numbers rasmussen has a strong bias. I know I had a couple typos but you understand the differrence between anecdotal and statisical evidence?
nate Silver:While waiting for the remaining results to trickle in from states like Colorado and Alaska, I did a quick check on the accuracy of polls from the firm Rasmussen Reports, which came under heavy criticism this year — including from FiveThirtyEight — because its polls showed a strong lean toward Republican candidates.
Indeed, Rasmussen polls quite consistently turned out to overstate the standing of Republicans tonight. Of the roughly 100 polls released by Rasmussen or its subsidiary Pulse Opinion Research in the final 21 days of the campaign, roughly 70 to 75 percent overestimated the performance of Republican candidates, and on average they were biased against Democrats by 3 to 4 points.
Every pollster is entitled to a bad cycle now and again — and Rasmussen has had some good cycles in the past. But their polling took a major downturn this year.
