Nate Silver just happens to be the "in" guy because he got lucky in his very first foray into polling in 2008. Prior to that, he was a baseball stats guru with known leftist political leanings.
The guy constantly hedges his bets, so one can always find something he predicted that will make him look good.
For example, even though on one hand he predicted a GOP gain of 54 seats in the House in 2010 (most polls did as well or better) - the actual gain was 63 seats - Silver did something he is well-known for. He published an alternative prediction that had it happened, he knew he would have been hailed as a true genius among political prognosticators.
