For many years Lyndon Johnson was he who must not be named. His name was, literally, not mentioned by Democrats. Before him Harry Truman had that status until his rehabilitation and after him Jimmy Carter has held something of that status, a treatment that is only slowly abating.
I think that LBJ is due for rehabilitation. I never liked him but I do feel he was the most masterful president of my lifetime. I suspect it will take another couple of decades and the passing from prominence of the Baby Boomers who demonstrated against Johnson in the streets before the corrective reassessment takes place.
You could do worse than reading Richard Cohen’s column today to understand why I think as I do. I don’t think that we need experts for presidents. I think we need people who want to do the dirty, nitty-gritty work of being president.
