A political analyst and blogger for the New York Times, Silver came to international prominence during the 2012 US presidential campaign. The consensus in the closing stages of the campaign was that the result would be close. Silver bucked this with predictions of a solid Obama win, and came under political attack from conservative analysts. He correctly forecast the winner in all 50 states. He is the author of The Signal and the Noise: Why So Many Prediction Fail—but Some Don’t (Allen Lane, 2012).
