That makes sense. I didn't really think it was the right definition for
Nash equilibria. That's why I put "Nash" in quotes in my last posting. So,
the "group strategy equilibrium" is what we're talking about. That's fine.
I think that group strategy equilibria are useful to talk about, probably
more useful than the Nash equilibria... since nearly all Votes in a large
electorate qualify as Nash equilibria, as you defined it above. Let's keep
talking about group strategy equilibria.
