Thrilled to announce my first book, "Why We're Polarized," drops in January. I'll have more tour info as we get closer, but more deets — and pre-order info! — here: simonandschusterpublishing.com/why-were-polar… 
It feels impossible to describe in a few tweets a project I've been working on for years, but here goes: American politics isn't broken. It's working as structured. We need to understand that structure, and the incentives of the players in it.
At the core of this story is "identity politics," but not the narrow, weaponized version we tend to hear about. We need to understand identity much more broadly, and see the way majoritarian political identities work, and why they're getting so much stronger.
~A lot~ of the way political institutions work now is by activating and reinforcing certain political identities. And that sets of feedback loops where the institutions polarize, an that further polarizes the public, which forces institutions to polarize more, which further...
Anyway. Much more to come on all this. But I think and hope it'll be valuable for people, and at the very least, there'll be a lot to argue with in it. You can pre-order from your favorite bookseller here: simonandschusterpublishing.com/why-were-polar…
