I’m afraid you’re right. At least McCabe would be in cuffs by now if anything of substance was going to happen. Barr may be playing some 3D chess.
Sessions served notice on day one that he would recuse himself and do nothing about the Deep State.
Sessions also served notice in early 2018, when in his memo, he stated that Huber's tasks would (only) be to review and report.
It was the Hope Porn Pushers who made up BS stories about Sessions and Huber doing things behind the scenes. And it was the gullible, who believed it.
About Barr, he has yet to indicate that he will not investigate and prosecute. He is certainly saying the right thins. For him, on the matter of Deep State prosecutions, it's TBD.
If that were to be true - and of course you posit a ridiculous charge - Barr still is a thousand percent better than Sleepy Jeff based on his concluding the Mueller witch hunt.
