Longer summary
Scott Alexander reviews Ezra Klein's book 'Why We're Polarized', which examines the historical and structural reasons for increasing political polarization in the United States. The book argues that the realignment of the Dixiecrats from Democrat to Republican in the 1960s allowed natural polarization to occur. Klein discusses factors like identity alignment, nationalization of politics, and negative partisanship as drivers of polarization. Scott finds some of Klein's arguments unconvincing, particularly regarding Republicans, and wishes for more international comparisons. He concludes that while the book asks important questions about polarization as a key political problem, it doesn't provide many clear answers.
