This will be Obama’s chance to actually be like Lincoln:
Declare war on the seceding state, announce martial law and suspend habeas corpus, and then invade Texas with the United States military.
Unlike the first War of Secession, however, I predict this one would last about 36 hours. (I don’t care how many guns the Texas national guard might have: you do not mess with the US military.)
Perry is obviously a complete moron.
Does threat of secession qualify as sedition?
