Party Polarisation

In Polarization: What Everyone Needs to Know Nolan McCarty takes listeners through what scholars know and don't know about the origins, development, and implications of our rising political conflicts, delving into social, economic, and geographic determinants of polarization in the United States. While the current political climate seems to suggest that extreme views are becoming more popular, McCarty also argues that, contrary to popular belief, the 2016 election was a natural outgrowth of 40 years of polarized politics, rather than a significant break with the past.
