Somehow I'd heard that a decisive factor in the 1920 election was women's suffrage, and that the vote had gone to Warren Harding because of his tremendous sex appeal. I've looked at Warren's picture, and all I can say is, Whoa! Maybe you had to see him with his shirt off. He was studlier-looking than Cox, I'll give him that, but that's not saying much.
Eugene Debs ran on the Socialist Party ticket but his campaign was hampered by being on the Socialist Party ticket. Also the fact he was in prison. Nevertheless, he got almost a million write-in votes.
After the Great War, people were pretty much sick of Democrats, and responded to Harding's call for a return to "normalcy." (No one called for a return to normalcy of English usage.)
The election was less about Harding vs Cox, than a referendum on Wilson. Wilson blamed German-Americans and Irish-Americans for rejection of the League of Nations, saying, "anyone who carries a hyphen with him, carries a dagger that he is ready to plunge into the vitals of this Republic whenever he gets ready." (Thank goodness we don't have any hyphenated Americans these days.)
Woodrow's remarks did little to win the love of German- and Irish-Americans; moreover ,word was beginning to get out that the last years of Wilson's presidency, the executive branch had effectively been under the control of the first lady.
No one seems to have asked Cox where he stood on the issue of a major cover-up a president's physical disability. Cox's running mate was Franklin Roosevelt.
Democrats took the high road during the campaign, insinuating that Harding had "negro blood," but voters ignored this pertinent issue. They were tired of warfare and international relations and ready to get down to the real business of American government: kickbacks, influence-peddling, and graft.
