Is the nation becoming more divided? Look at county-level voting from the 1920 elections to see an example of a divided nation. A century ago, Republican Warren Harding coasted to a landslide victory over James M. Cox. Harding lost fewer than 20 counties north of the Mason-Dixon line.
Harding also swept counties in the entire states of California, Oregon, Washington, Montana, Wyoming, Colorado, Kansas, Nebraska, North Dakota, Minnesota and Wisconsin. Cox retired from electoral politics to build a media empire; his running mate fell ill with polio the summer after the election, but Franklin D. Roosevelt eventually found other political work.
