American politics feels like a war between two alien tribes. But what if the problem isn’t that we’ve all gone crazy? In Why We’re Polarized, Ezra Klein delivers a stunning diagnosis of our fractured nation, revealing how the political system itself is a polarization machine. He masterfully shows how our identities—Democrat or Republican—have become “mega-identities” that dictate everything. This isn’t just another book about division; it’s the essential guide to understanding the psychological and structural forces that are tearing America apart from the inside out.
