One of my favorite sites is fivethirtyeight.com (reference to the Electoral College). It has moved to the NYTimes and can be found here. Nate Silver has made a career of using statistics to make political forecasts. Here, for example, is his statistical forecast that Dems will lose 6-7 seats in the US Senate this fall. You don't have to understand stats to like this site. This addition to the NYTimes is just another reason why the paper might get away with its pay service that it will be starting in January. You will, though, be able to use links for your students who will NOT have to pay.
