Which is the most ideologically diverse American city?

Tyler Cowen:

1. Houston. It still has plenty of Texas conservatives, but enough non-conservatives to elect a lesbian mayor. Mexicans fit along a political spectrum of their own.

2. Washington, D.C. and environs. The intellectual class in this city is about half conservative/Republican/libertarian and always will be — just don’t think too hard about who actually lives here! Most of all, everyone is used to the fact that there are oodles and oodles of forces on the other side of the debate. No one flips out over this. Even the media types have a reasonable amount of non-left representation.
