The Texas secession question got me thinking, what about the opposite? Can the US expell a state, like Texas? Not that it's a good idea at all, about as good as secession, but what if we decided that we wanted to cut some state loose? Could we do it? Maybe we decided we needed a Mexico buffer region where the immigration dispute could be handled by a less divided country. Let Texas play shoot 'em up at the Mexico border and we can claim innocence. We'll send them a condemnation letter or threaten them sternly about it. Can we do that? Expell a state?
