Didn't he run on the Libertarian Party ticket in 1980?
Yes, he was the vice-presidential nominee.
Also, with regards to the term
social liberal, this is what Wikipedia has to say:
http://en.wikipedia.org/wiki/Social_liberalismI know that our political discourse has evolved such that
social liberal has come to mean "one who believes that the government should have less control with regard to non-economic issues", but the use of political terms to refer to things other than their standard meanings that one would find if one looked the terms up annoys me. A similar case is many modern Americans' use of the word
corporatist.
Social liberalism, in other words, properly refers to the whole of what we in the United States call
liberalism, not just its views on a specific set of issues.
