Some Prohibitionists and other Bryan supporters tried to convince the three-time presidential candidate to enter the 1920 presidential election and a "Literary Digest" poll taken in mid-1920 ranked Bryan as the fourth-most popular potential Democratic candidate. Bryan, however, declined to seek public office, writing "if I can help this world to banish alcohol and after that to banish war ... no office, no Presidency, can offer the honors that will be mine." He attended the 1920 Democratic National Convention as a delegate from Nebraska, but was disappointed by the nomination of Governor James M. Cox, who had not supported ratification of the Eighteenth Amendment. Bryan declined the presidential nomination of the Prohibition Party and refused to campaign for Cox, making the 1920 campaign the first presidential contest in over thirty years in which he did not actively campaign.
