Instead of coalition and compromise, the solution may be to splinter and separate. Allow people to live in any political jurisdiction they choose. Let socialists self-select to live with other socialists. Let libertarians self-select to live with other libertarians. Accommodate the Long Tail by allowing people to choose their political jurisdiction, rather than have it dictated by geography. That is what I mean by "virtual Federalism."
That could be real interesting, being able to choose your political jurisdiction without moving. Might get a lot more people involved. HT Instapundit
