Yeah, I think Barr is beginning to realize that he hitched his wagon to the wrong 'star'.
He may be opportunistic pond scum, but he's not stupid. I think he's going to try to claw his way back to some semblance of 'respectability'.
He had a long career at the DOJ as well as being Depty AG & AG during the Bush #1 Admin. But after his stint as Scrotus' personal Uriah Heep he probably won't be able to get a job in the DoJ as a dog catcher. His credibility is shot to hell.
