I have been studying the issue for months, and I have come to a conclusion that many people will not like, but the facts point that way.
Sessions is a coward.
If he actually did his job, as the Chief Law Enforcement Officer of the United States, he would have to confront the incredible evil and criminality that infests the political class. That will take great courage, and Jeff Sessions is filled with fear and cowardice in the face of this challenge.
It is what it is.
People can dispute this, and blather on about how "brave" Sessions has been with this or that issue. It is meaningless, because he is at the crossroads, and he failed to act. He ran for cover, and attempted to clothe himself in self-righteousness and charades of "honor" and "integrity." It is all a smoke screen.
Sessions simply lacks the intestinal fortitude to stand up to abject Evil. He was, and is, willing to allow President Trump to die by a thousand cuts, rather than do the job the President entrusted him to do.
