Can we encourage the Calexit movement? If they vote to secede, we can either let them go (on condition we get to keep some military bases, a free trade agreement, and the California peso pegged to the dollar for at least a decade, and border counties get to have plebiscites on remaining in the U.S. by joining a neighboring state), or we can refuse and when some hot-heads do something against Federal officers or facilities, give them the treatment the Confederacy got, complete with radical reconstruction. Either way it's 54 'rat votes in the electoral college and a heavily 'rat congressional delegation gone (at least until reconstruction is complete).
