In the special election, Brock was elected to fulfill the balance of Tyson's term, but he did not run for the full six-year term that was on the ballot at the same time, and his service as a U.S. senator ended on March 3, 1931. He was succeeded by Cordell Hull who won the succeeding term ballot.[2][3]
