Remember when those two New Black Panthers were under indictment by the Bush DOJ for voter intimidation? They were standing armed in paramilitary gear outside the polling place. Yeah, the Obama DOJ dropped that case like a hot potato as soon as he was sworn in.
The corruption of the FBI and DOJ, into a completely political entity was trending for many years, with the growth of leftist/progressive government, and the collection of political power in DC and Fed.gov. RINOs like Bush helped, by standing aside, watching, and often, helping its growth.
Obama and Holder smashed down any remaining walls, and turned the DOJ into Fed.gov's woke police force.
Maybe I am wrong, but I can not see how it can simply be reversed.
