Rather than them seceding, let's help them along. I vote we blockade every interstate leading into and out of every major blue city in America. With the "just in time" inventory system this country utilizes, we'll see how they feel after 2 days with no new food coming into their rotting cities. I am sure we can also arrange to cut off their water. Let's see, New York, LA, San Francisco, Seattle, Boston, Miami should just about do it. Bring your guns boys, we're gonna party...:)
