Won’t happen. What’s he going to do, have US Army soldiers occupy Boards of Vital Statistics, and have some brownbar hand out marriage licenses to sodomite couples? Moreover, most military these days come from that part of the country that liberal elites call “Flyoverland” or “Jeebusland.” Who will they side with? Open question. It’s tough to get regular troops to shoot civilians. The Soviets tried it during the Rostov bread riots in 1962 and the soldiers refused! Had to use MVD troops for that. Plus, putting down a state uprising looks bad on the 24 hour news cycle. Messy business. DC, like most bullies, will back down.
Wait until we have another Kent State incident. It will get real ugly, real fast.
