Political Polarization Symposium

We live in a polarized political age, where support for extreme political views has increased relative to support for moderate ones. In Congress, Republicans and Democrats are more divided along ideological lines than at any point since the end of Reconstruction. In the public, Republicans and Democrats are increasingly divided along ideological lines, as the share of Americans who express consistently conservative or consistently liberal opinions has doubled over the past two decades. Fears about the growing influence of partisan polarization abound, as threats to democratic government become more common. The PIPE Symposium on Political Polarization brings together leading scholars from across the nation to consider the history, sources, and causes of growing ideological differences, both domestic and global, as a way of understanding how such polarization might be combated in the future.
