It's hard for me to see any problem with this. Pritmuch the only states supporting the Interstate Compact were ones who were going to vote Blue anyway. But hopefully this will add more tools to the toolbox for potentially preventing any Red states from getting a bug up their ass anyway. Heh.
Yeah, this is basically a victory for states' rights. Well, the authority to exercise them, not necessarily the wisdom of this particular legislation.
I can't remember what thread I posted in, but my own view on this is that it is a terrible idea and each state needs to realize that on its own.
