1916 United States elections
The election occurred during the Fourth Party System, six months before the United States entered World War I.Democratic President Woodrow Wilson defeated the Republican nominee, former Supreme Court Justice Charles Evans Hughes, in the presidential election.Republicans won several Northern states, but Wilson's success in the rest of the country gave him a small margin in the electoral college and the popular vote.Wilson's running mate, Thomas R. Marshall, was the first sitting vice president to win re-election since John C. Calhoun.In the second Senate election since the ratification of the 17th Amendment, Republicans made minor gains, but Democrats retained a solid majority.
