1918 United States Senate elections

The 1918 United States Senate elections were held throughout 1918,^[a] the midpoint of Woodrow Wilson's second term as president. This was the first election since the ratification of the 17th Amendment that all 32 Class 2 senators were subject to direct or popular election, making them the final class under the old system of being selected by state legislatures. Special elections were also held to fill vacancies.
