Journalist Ezra Klein is the editor-at-large and co-founder of Vox.com. His new book, Why We're Polarized, argues that our political system isn't broken: Its very design made the damaging current cultural divide inevitable.

Uncivil Agreement: How Politics Became Our Identity by Lilliana Mason (2018).

This is the academic book on identity polarization. It's a touchstone for understanding politics in this era, and one of the works that have done the most to shape my thinking.
