Whirlibird, it will indeed get interesting. My guess is that what we will see first is not an actual secession but rather a constitutional crisis caused by a State voiding Federal jurisdiction in some fashion. It might first go to the Supreme Court and if so, clearly one side will win and one will lose. The real crisis will then depend upon what the losing side does. It will be one of the Western States that goes first, perhaps over Federal control of public lands. The whole secession issue is not even a topic in the Eastern US.
