By 1934 Coughlin was perhaps the most prominent Roman Catholic speaker on political and financial issues, with a radio audience that reached millions of people every week. When he began criticizing the New Deal that year, Roosevelt sent Joseph P. Kennedy and Frank Murphy, prominent Irish Catholics, to try to tone him down. Ignoring them, Coughlin began denouncing Roosevelt as a tool of Wall Street. Coughlin supported Huey Long until Long was killed in 1935, and then supported William Lemke's third party in 1936. As Coughlin turned into a bitter opponent of the New Deal, his radio talks escalated in vehemence against Roosevelt, capitalists and "Jewish conspirators". He was initially supported, and later – after turning on Roosevelt - opposed in his efforts by another nationally known priest, Monsignor John A. Ryan.<10> Kennedy, who strongly supported the New Deal, warned as early as 1933 that Coughlin was "becoming a very dangerous proposition" as an opponent of Roosevelt and "an out and out demagogue." Kennedy worked with Roosevelt, Bishop Francis Spellman and Eugenio Cardinal Pacelli (the future Pope Pius XII) in a successful effort to get the Vatican to silence Coughlin in 1936.<11> In 1940-41, reversing his own views, Kennedy attacked the isolationism of Coughlin and of aviator Charles Lindbergh.<12>
In 1935, Coughlin proclaimed, "I have dedicated my life to fight against the heinous rottenness of modern capitalism because it robs the laborer of this world's goods. But blow for blow I shall strike against Communism, because it robs us of the next world's happiness."<13> He accused Roosevelt of "leaning toward international socialism on the Spanish question." Coughlin founded the National Union for Social Justice, an organization with a strong following among nativists and opponents of the Federal Reserve, especially in the Midwest. As Michael Kazin notes, Coughlinites saw Wall Street and Communism as twin faces of a secular Satan. Coughlinites believed that they were defending those people who cohered more through piety, economic frustration, and a common dread of powerful, modernizing enemies than through any class identity.<14>
One of Coughlin's campaign slogans was: "Less care for internationalism and more concern for national prosperity" which went well with the 1930s isolationist movement in the United States. Coughlin's organization especially appealed to Irish Catholics. In 1936, Coughlin helped found a short-lived political party, the Union Party, which nominated William Lemke for President. Coughlin promised to retire if Lemke did not get nine million votes, and when he received only 900,000 Coughlin stopped broadcasting briefly. He resumed in 1937.
