Nate Silver's 538

Three years ago baseball statistician Nate Silver took his numbers to the presidential election trying to figure out who was going to be the next president and taking the leap of being the first person to accurately figure out the electoral college.  In the process he very quickly became widely respected and wasn't far off in the prediction.  He has done so well that the NYTimes has bought his blog and he has a book on the way.  If you want to see the role of statistics in politics (which is, by the way, what political scientists do), it is a great and very helpful teaching tool. His blog is called 538.com.
