The 1926 United States Senate election in Indiana took place on November 2, 1926. Incumbent Republican Senator James E. Watson was re-elected to a second full term in office over Democratic attorney Albert Stump.
Frederick ran with the backing of former U.S. Senator and party boss Thomas Taggart. Curry ran primarily for the modification of the state's "bone dry" prohibition law, rather than national prohibition.[1]
In a non-binding primary, Cullop won with Stump finishing second.[1]
On the first convention ballot, Frederick was first with Cullop second. On the second ballot, Stump passed Cullop for second place. On the third, there was a stampede to his candidacy as Frederick and Cullop supporters abandoned their candidates for Stump.[1]
