What would have been the consequences of the election of James M Cox to Presidency of United States in 1920?
Make Hughes win in 1916. If he takes America into war, as Wilson did, then by 1920 the annoyance over wartime sacrifices, and general desire to get back to normal, will hurt the Republicans much as OTL they hurt the Democrats. The obvious candidate would be ex-President Wilson, but if health problems eliminate him, then Cox is as likely as anyone.
Will Cox be forced to govern more Conservatively in this national mood, do you think?
Would a President Cox have made a renewed push for US membership (allowing for reservations, unlike Wilson) in the League of Nations?
True that; I was looking for a way for Cox to build a respectable structure from the ruins left by the collapse of Wilson's palatial ambition.
