About the 1917 governor elections

The United States declared war on Germany in April 1917, and the draft, war bonds and new federal powers over the economy followed. Only two states held governor elections that fall. In Massachusetts, Republican Samuel W. McCall won a third one-year term by about 23 points over Frederick W. Mansfield. In Virginia, Democrat Westmoreland Davis won by about 44 points over T. J. Muncy. Davis, a farm journal publisher, won the Democratic primary as an outsider against the state's organization candidates, and the general election was a formality in a state where Democrats faced little serious opposition. With most attention on the war in Europe, the 1917 governor elections said little about national politics. The larger test of the war's effect on the parties came in the 1918 midterms.

Margin: the Democrat's share of all votes minus the Republican's. Margins are Democrat minus Republican, of all votes. Certified results, from the states' own archives, the MIT Election Data and Science Lab, Heideman (2026) and Algara & Amlani (2021). By county: "As they were" draws each county as it stood on election day; "Today's" shares the old votes among today's counties by area, so its county detail is an estimate.
