Nelson unsuccessfully ran for the United States Senate as a Republican in 1928 against Henrik Shipstead (receiving 33.4% of the vote), but was elected fourteen years later, in November 1942 to finish out the term of deceased Senator Ernest Lundeen, which had temporarily been filled by appointee Joseph H. Ball (who won the November 1942 election for the full six-year term from 1943 to 1949).
In 1940, he ran for the United States Senate against Henrik Shipstead, an incumbent senator who defected from the Farmer Labor Party to join the Republicans.
