Sorry, they're furrinErs now, like Meskins. We're building a wall around Louisiana to keep out the riffraff.
What's funny is that of all the states that might have a chance to go it on their own, Louisiana has got to be at the bottom of the list or near it, with the likes of Mississippi and Alabama. They are failed states in waiting.
I know Foreign Policy magazine did a story about this once, what realistically would happen if a state seceeded (short answer: they'd be sorry in a hurry) but somebody should do a state by state analysis on what would happen in each case, it would be interesting. I subscribe to FP so if they do a follow up, I'll post a link here.
