Before the primary, incumbent governor Henry Horner, a Democrat, opted not to seek a third term. In October, before the general election, his death in office made John Henry Stelle assume the governorship. However, Stelle had previously failed to win the Democratic nomination in the primary.

Republican Dwight H. Green won the election.
