The Supreme Court then dissolves itself & the judiciary, saying that they have no authority anymore because no Constitution.
Trump & Co say we'll keep the courts, but purge all judges not appointed by me or someone named Bush. And there is no law but what we promulgate.
Then we purge the Congress of all the "enemies within". Some folks who lost their races might be glad they aren't in DC at that particular moment.
Then we declare the military must swear loyalty to Trump directly.
