That's a good example of the kind of things that would distract Trump from getting anything of real substance actually accomplished.
Hillary, Pelosi, and the Bidens would all be has-beens irrelevant to the future of the country in 2025. And exactly who is going to make the decision to prosecute them? Trump himself? The guy has the attention span of a gnat.
Trump or no trump, what we are seeing is a pervasive rot in our government, enabled by the Unconstitutional concentration of power in an entrenched bureaucracy which has taken on the powers of legislation, enforcement, and judgement to itself. It is this tumor, this tyranny, which wraps itself in the trimmings of a Republic and goes through the theater of elections (although not so much entrusted to the people any more), which is the real threat.
Yes we have problems, but rather than paint the nails and get the dye job, how about we make sure the patient lives. Until the tumor is removed (which Barr would see as "chaos"--he's been part of it for a while). No other problems will be able to be solved.
If that means prosecuting doddering old people who have lived high on the hog their working lives on our dime in the creation of this evil, so be it. Let them serve their sentences in a max security home, not of their own devising. It is the acts which must be deterred, prosecuted and punished, and those who did them did them.
If Hitler or Mengle were found alive tomorrow would they still get the gallows?
Damned right they would.
