Barr does nothing. The minute the dems get in power they will be prosecuting and throwing Republicans in jail as far as the eye can see.
And the irony is that, at least per one report just after Poppy’s funeral, which is when Barr came up as the AG nominee (with Joe DiGenova flogging him to Trump), the Jeb and W generation of Bushes decided they didn’t want to continue their father’s criminal business and came to a truce with the Trump family. (Remember all the Bushes with their extended nostalia visit to the WH?) The report at the time said that Barr, long a Bush family/CIA coverup fixer and close personal friend of Rober Mueller, was put in as part of the deal by the Bushes to be an enforcer of the truce terms. (That neither family would face serious charges.)
Gruseome and true.
Someone can then say to the Dems "But wait, doesn't that look political?" And hear uproarious laughter bringing the Dems to the knees in hysterics.
By the way, when gangsters have no need for the hit men who did their jobs but could now recall it all on the witness stand someday, the triggermen get killed. Can't Barr and Durham be jailed just like the NY DA will do to President Trump, no longer a "sitting President."?
