An opponent of the British Empire, Hearst opposed American involvement in the First World War and attacked the formation of the League of Nations. His newspapers abstained from endorsing any candidate in 1920 and 1924. Hearst's last bid for office came in 1922, when he was backed by Tammany Hall leaders for the U.S. Senate nomination in New York. Al Smith vetoed this, earning the lasting enmity of Hearst. Although Hearst shared Smith's opposition to Prohibition, he swung his papers behind Herbert Hoover in the 1928 presidential election. Hearst's support for Franklin D. Roosevelt at the 1932 Democratic National Convention, via his allies William Gibbs McAdoo and John Nance Garner, can also be seen as part of his vendetta against Smith, who was an opponent of Roosevelt's at that convention.
