Well said. I would also like to point out something that has changed regarding the DOJ now than, saw, a few months ago:
Lafayette Square.
Barr's involvement in such (and you can be your ass he was, because otherwise he wouldn't be trying to distance himself from it) is a pretty universally condemned action - as you can see by the number of Republican defections - and it has had the effect of revealing Barr for the toady he is. It's difficult for people to take a claim of "Biden is working for Ukraine" seriously from an AG under investigation for using chemical weapons on peaceful demonstrators and clergy.
Basically, the next few months are going to have to be spent on damage control over these protests. And Trump doesn't do damage control.
