Why not? Surely, that would be the best thing not just for us, but for the Lefties too. It would certainly be more democratic. As it is now, we get in power and impose our beliefs on them against their will. Then they get into power and do the exact same thing. Letting Massachusetts control Texas or vice-versa really isn’t governing by the “consent of the governed.”
Another good way of saying that a return to federalism is the only way to bridge this divide AND preserve the union, quite nicely, too.
