Henry Olsen, a senior fellow at the Ethics and Public Policy Center, studies and provides commentary on American politics. Mr. Olsen is an opinion columnist for The Washington Post, where he writes daily pieces focusing on politics, populism, foreign affairs and American conservative thought. He is also the author of The Working Class Republican: Ronald Reagan and the Return of Blue-Collar Conservatism and The Four Faces of the Republican Party, co-authored with Dante Scala.

His predictions of the 2008, 2010, 2012, 2014, 2016, and 2018 elections were particularly praised for their remarkable accuracy. In the 2016 campaign, he accurately identified the factors fueling the rise of Donald Trump early in the race, and his election-eve predictions were among the most accurate of any major analyst or commentator.

Mr. Olsen started his career as a political consultant at the California firm of Hoffenblum-Mollrich. He then worked with the California State Assembly Republican Caucus before attending law school. He served as a law clerk to the Honorable Danny J. Boggs on the U.S. Court of Appeals for the Sixth Circuit and as an associate at Dechert, Price & Rhoads. He has a B.A. from Claremont McKenna College and a J.D. from the University of Chicago Law School, where he served as Comment Editor for the University of Chicago Law Review.
