A bit more on serious nutball Paleo libertarian Rothbard:

Rothbard split with the Radical Caucus at the 1983 national convention over cultural issues, and aligned himself with what he called the “rightwing populist” wing of the party, notably Lew Rockwell and Ron Paul, who ran for President on the Libertarian Party ticket in 1988, and again on the Republican ticket in 2008.[citation needed]

In 1989, Rothbard left the Libertarian Party and began building bridges to the post-Cold War anti-interventionist right, calling himself a paleolibertarian.[23] He was the founding president of the conservative-libertarian John Randolph Club and supported the presidential campaign of Pat Buchanan in 1992, saying “with Pat Buchanan as our leader, we shall break the clock of social democracy.”[24] However, later he became disillusioned and said Buchanan developed too much faith in economic planning and centralized state power.
