This good. The only state their model got wrong was Indiana, where they expected a narrow Obama loss. He won the state by a hair. Nate Silver owned this election on the polling front: one young guy with a background in baseball stats beat out the mainstream media in a couple of months. And he beat out the old web: I mean if you consider the total joke of Drudge's recent coverage and compare it with Silver's, you realize that the web is a brutal competitive medium where only the best survive - and they are only as good as their last few posts.
If you want to know why newspapers are dying: that's why. They're just not as good as the web at its best. This election proved that beyond any doubt. For the record, I think the WSJ and the WaPo and the NYT and the Anchorage Daily News rocked in this election. Most of the rest of the old media: not so much.
