Nathaniel Read "Nate" Silver is an American statistician and writer who analyzes baseball and elections. He is currently the editor-in-chief of ESPN's FiveThirtyEight blog and a Special Correspondent for ABC News. Silver first gained public recognition for developing PECOTA, a system for forecasting the performance and career development of Major League Baseball players, which he sold to and then managed for Baseball Prospectus from 2003 to 2009.
In 2007, writing under the pseudonym "Poblano", Silver began to publish analyses and predictions related to the 2008 United States presidential election. At first this work appeared on the political blog Daily Kos, but in March 2008 Silver established his own website, FiveThirtyEight.com. By summer of that year, after he revealed his identity to his readers, he began to appear as an electoral and political analyst in national print, online, and cable news media.
