1926 US Senate election in Iowa

Smith W. Brookhart (Republican) beat Claude R. Porter (Democrat) in Iowa in 1926, 56.5% to 43.3%, a margin of 13.2 points and 75,540 votes.

David W. Stewart (Republican) won in Iowa in 1926 with 100.0% of the vote and no opponent from the other main party. (This was a special election.)

The Republican hold continued from 1920, when Albert B. Cummins won.

Republicans led in 80 of the 99 counties as they stood then and Democrats in 19. The largest, Polk, cast 24,793 votes and went to the Republican by 19.7 points. The closest was Wapello, where 34 votes separated the two parties.

Early projection, based on early and incomplete polling: the likely matchups, each weighted by the betting markets' odds of both nominations, not a result. Each county is its 2024 presidential margin moved by its state's projected swing; set a national vote and every state, district and county moves by the same amount from our projection. Colours run in 100 steps from a safe Republican to a safe Democratic margin. Boundaries: US Census Bureau.
