Is Nate Silver Fudging the poll? Maybe the Democrats are ahead?

22. Nate's reputation is based on a very short resume in political predictions, two Presidential cycles

make up the bulk of his public image, but the fact is he is not as exacting in Congressional races, which is what we are talking about and in reality, two elections called well shortly prior to the elections does not support deeming him oracular in his prognostications.
In 2010, Nate was wrong about 3 very important Senate races and off on his prediction in the House by 11 seats, Republicans won 63 seats when his prediction was 52.
2010 is in fact the ONLY midterm election for which we have Nate's predictions. I'm no numbers guy, but I don't think one outing makes a trend, and I think that if that one attempt failed it is rather silly to assume the next one is going to be hyper accurate.
His reputation is strong but it is short. Putting too much weight on his predictions just does not seem to pass the test of reason.
