Never said eliminate our courts, stop being so dramatic. Martial law can be declared like Lincoln did, he didn’t eliminate the courts.
The left doesn’t care about the Constitution, Obama once complained that it shackles government as if that were a bad thing. Our government has been infiltrated with officials who work to undermine the Constitution at every turn. The criminal justice system and the judicial branch have been compromised, the left has installed judges who do not rule according to law, and states attorneys who refuse to prosecute in blue states. The status quo isn’t going to right the ship.
Stop, stop, stop with Obama. No one is using him or his administration as guideposts of judicial rectitude.
As to Lincoln, his action was questionable at best, but at any rate, in the case Ex parte Milligan (1866), the Supreme Court that ruled that the use of military tribunals to try civilians when civil courts are operating is unconstitutional.
So yeah, if you want to trash our Constitution, have at it.
