Both are liberals but Bourdain is open about his hatred of America.
I follow Tony on all his shows and also on eGullet where he is a pretty active forum member and I don’t see him hating America.
He also strikes me as pretty libertarian. He is constantly trashing hippies, he has gone to war against the food nazis in New York, and you should have seen the show with him and Ted Nugent.
Now, he isn’t conservative.. he is socially libertarian on a lot of things, pro drugs, pro open borders, etc so I’m not putting him on a political platform.
