William F. Buckley did.
I just made a post on another thread about what Buckley thought about Buchanan. It may have been in the famous essay everyone quotes. Buckley wrote: “Buchanan is more of a prophet than a politician, and if the country is to be saved, it will be along the lines laid down by Buchanan.” That quote is from memory, but is probably 90% accurate. Joseph Sobran critized Buckley about the anti-Semitism thing; Buckley fired him, but they later got together and reconciled. I’ve always been a Buckley fan, and I kept up with him.
