Matthew Levendusky

Levendusky was raised in Pittsburgh, Pennsylvania, later attending Pennsylvania State University, where he graduated with a degree in political science in 2001. After graduating, he entered the political science PhD program at Stanford University. He was a runner-up for a National Science Foundation grant to attend Stanford, where he obtained a Ph.D. in political science.[1] After completing his dissertation in 2006, Levendusky spent a year as a postdoctoral research associate at Yale University in the Center for the Study of American Politics in the Institution for Social and Policy Studies. Levendusky began working at the University of Pennsylvania as an assistant professor in the political science department in 2007.

The Partisan Sort: How Liberals Became Democrats and Conservatives Became Republicans, is a book on the phenomenon of growing political polarization in the United States.[2][3][4] Levendusky finds that while a small number have become more extreme over time, most contemporary Americans maintain relatively similar views to those in previous generations. What has changed is the way people sort themselves into parties. Previously, many liberals identified as Republicans and many conservatives identified as Democrats. More recently, the parties have become more ideologically pure and encouraged people to think of themselves in that way as well. Thus, voters have been "sorting" into Democrats and Republicans and eliminated much of the middle ground that existed in previous generations.

Reception for the book was positive.[5][6]
