One particularly intriguing quote about LBJ came from a contemporary during his stint as an assistant to Representative Dick Kleberg during the early 1930s. Johnson was described as follows: "I don't think Lyndon was either a conservative or a liberal. I think he was whatever he felt he needed to be. Winning is the name of the game. I have no doubt he could become either an ultra-liberal or an ultra-conservative if that would have brought victory."
Now, I am not sure such a propensity for change would work well in modern politics lest the politician be labeled as a hypocrite or flip-flopper. But re-read that quote, substituting "bull" for conservative and "bear" for liberal. Makes for a pretty good trading mentality, doesn't it?
