Elections in Illinois |

![]() |
The 1930 United States Senate election in Illinois took place on November 4, 1930.[1]
Incumbent Republican Charles S. Deneen was unseated in the Republican Party's primary election. Democrat J. Hamilton Lewis, who previously held this Senate seat from 1913 to 1919, won a second nonconsecutive term.
This election was notable as being the first instance in which a major party nominated a female candidate for United States Senate, with Ruth Hanna McCormick, widow of Deneen's predecessor in this seat Medill McCormick, becoming the Republican nominee after defeating Deneen in the Republican party’s primary election.
This was the first time since the Seventeenth Amendment to the United States Constitution made U.S. senators popularly elected that a Democrat won a U.S. Senate election in the state of Illinois.
