Nate Silver is one of the people behind "Baseball Prospectus," the annual book that tries to forecast player performance on an annual basis. The book is well done and nicely written; it's obvious the writers know what they are talking about and have a lot of fun doing it.
Silver apparently is doing other things in his "spare time" -- politics. He was just written up in Newsweek for being on target in his predictions for primaries.
I went searching for a sample of his work, and found this -- a very impressive page of notes on the upcoming election.
If you have an interest in elections, this one might be worth a bookmark.
