Well, I guess by "libertarian" you mean governed with more non-violence than violence.
Well, as I said, it's relative. George McGovern, my favorite off that list, proposed a guaranteed minimum income during his campaign - but so did Richard Nixon, though he obviously never fulfilled that pledge. Nixon's health-care plans were far to the left of McGovern's, and Nixon's military interventionism and stance on social issues (busing, Affirmative Action, etc.) were obviously unlibertarian. McGovern, on the hand, favored limited drug legalization, amnesty for draft dodgers, and took a state's-rights stance on the abortion issue. McGovern was clearly and obviously the more libertarian of the candidates, even if he wasn't a dogmatic Lew Rockwell-style 'paleolibertarian'.
