In 1886 elections were moved from odd years to even years. Beginning with the 1962 election, the term of the lieutenant governor increased from two to four years. Prior to the 1974 election, governors and lieutenant governors were elected on separate ballots. Marlene Johnson, elected in 1982 as the running mate of Rudy Perpich, was the first female lieutenant governor of Minnesota. All seven of her successors in that office have also been women.
