cybermgk: "The OP isn't arguing that the people of those states shouldn't attempt to change the law(s). It also isn't an argument for taking away State's Right's, not really. The OP is arguing why the Federal DOJ doesn't prosecute States, when they violate Federal Law, on a matter of which the Federal Government has preemption on."

Thank you for your understanding. That's exactly what I was saying!
As many of you here probably already know, the U.S.House passed a bipartisan bill on total reciprocity for the entire Country a few years back. Harry Reid refused to bring it to the floor of the U.S. Senate. By the way, it passed by a 2:1 margin, so it was heavily favored by both sides of the political divide. It would have solved all our problems going from one state to another. That's not the way I would like to get reciprocity( I'd prefer from the Supremes), but if that's the only way we can get it, I'd be satisfied.
