They would viciously go after President Trump and his family. Manufacture crimes to throw them in jail. They will want to send a signal to any populist candidate wealthy enough that's outside the uniparty's control to not even think about running for election.
Game over.
Barr was able to run out the clock on obvious in your face criminality that we have known about for years. He just appointed Durham special counsel so that President Trump's administration cannot release any information about the case to the public. Then Biden can come in and bury it deep never to be seen again. Thanks for fucking America over, Barr.
