Worst-case scenario, this is how it might play out:
1) Biden tries to federalize the Texas National Guard under Title 10.
2) At least one of the TX National Guard generals refuses the order (the general will claim Biden’s federalization under the circumstances constitutes illegal orders). Trump weighs in and people start getting HEATED.
3) Biden then invokes the insurrection act and tries to federalize all national guard troops - and Biden will claim state rebellion. Trump continues to weigh in and things escalate quickly - and they attempt to arrest Trump.
4) Abbot orders all TX law enforcement on duty and asks Sheriffs offices to start building posse’s (also known as militias).
5) The Texas house has emergency session because someone in the Austin area tries to impeach Abbot. Trump continues to weigh in and things heat up further.
6) TX courts are thrown into chaos.
7) Federal courts are thrown into chaos.
8) Other red states see their opportunity and start pushing back against the Federal Government and take it to varying degrees.
9) Biden declares martial law. Martial Law makes crazy people do crazy people things.
10) Red states do not comply.
...the end.
