I disagree with @atomheartbevo that this action by Abbott is wholly performative. It is performative, no argument there, but it is also a very good trial run to test just how state and federal military will react during a coup; a real coup that doesn't just use cos play cult crazies. If you think I'm being too Ledgey, no one except those cult crazies has suffered any punishment whatsoever. All of the GOP congresspersons, senators, planners (Roger Stone, Ali Alexander, Nick Fuentes, Michael Flynn, et al), donors, and such are still more than willing to keep trying.
The leadup to January 6th was filled with stumping by Ted Cruz, Josh Hawley, etc because of the January 5th Georgia Senate run-off between Loeffler and Warnock and the "Stop the Steal" campaign that began in November, 2020 was fully ramped up by then and all over social media, parroted by GOP reps (who then scrubbed their accounts). This drumbeat that Abbott began is going to keep pounding until something happens, and the GOP wants something to happen.
Dangerous times right now.
