I think Donuel meant Father Coughlin, a Catholic priest who promoted isolationism, was anti-New Deal, anti-Communist and anti-Semitic. He had a populist radio program through the 1930s until demoted by the Church in 1942. Actually, except for the anti-Semitism (I'm not sure about isolationism), Glenn Beck may share some of Coughlin's ideas in a context for today.
