Free Nate Silver

The point is, Nate Silver is under attack because his fivethirtyeight blog is forecasting a likely Obama victory.
Ezra Klein explains exactly what is going on, and does so quite persuasively, defending his fellow wonk. Ezra makes an immaculate free-market argument here, pointing out that Silvers influence is based on his excellent track record and that if someone came along with a better formula for predicting election outcomes that person would supplant Silver as the go-to numbers geek. If you dont like Silver, then build a better mousetrap.
And Ezra also makes the most important point: Silver is not saying Obama is definitely going to win. Silver is currently saying that in some scenarios Obama will win and in some scenarios Romney will win and the first batch of scenarios outnumber the second batch of scenarios by about 3 to 1.
