That would be Pat “you can’t kill Jews with gas, survivors are mentally ill” Buchanan. Moral voice of the 1992 GOP.
Pat Buchanan was hardly a “moral voice” for the GOP. He fared quite poorly in the GOP primaries that year, although he did get some notoriety after winning in NH. The major point is that he has been effectively drummed out of the Republican party, and his participation in subsequent presidential campaigns has been as a third party candidate.
