Dude! Phenomenal post!
LBJ had a few warts, but even as a liberal, I would take him over JFK every day of the week. Kennedy talked a good game about civil rights, but LBJ made it happen, knowing full well that he was exhausting damn near all the political capital he had to do it. He knew what he was doing would effectively throw any prospects of a run in '68 (as an incumbent no less) under the bus, but he did it anyway. That guy had balls of iron. Incredibly under-rated as a prez.
Now I have to give you the same spiel I gave Claude when he finally convinced me to read Haidt. Damn it, Neo, the last thing I want to do is read some 4-volume biography, but now you leave me no choice.
