You will find many, many Repubicans (and Federalists) with strong libertarian views - all you have to do is look - but the problem is far deeper than a simple "left v. right," as you clearly understand. As a companion thought, you might find A Grandfather's Wisdom: "We Must Stem This Tide of Radicalism" (Circa 1937-39) of more than passing interest, even though it was written 80 years ago. Upvoted.
