Extremism in the pursuit of the Presidency is an unpardonable vice. Moderation in the affairs of the nation is the highest virtue.
– Lyndon Johnson, the successful 1964 US presidential candidate (thanks to an article in Capitalism Magazine for the quotation)

you have got to be kidding me. by far the better quote is goldwaters a true liberterian
More to the point, what did Johnson do that was “moderate” about the affairs of the nation?
virtue and LBJ? The only Johnson quote I know is: “If anyone tells you he’s just a dumb country boy, keep your hand on your wallet.”
“Extremism in the pursuit of the Presidency is an unpardonable vice. ”
No one who pursued the presidency “moderately” became president.
Johnson would certainly know.
The author of that extremist Great Society socialist scheme that’s been slowly bankrupting America said THAT? Aaaaaargh!!
It was Goldwater who said that, not LBJ. The quote was also in Charlie Wilson’s War. Egads, that was a serious mistake!
