Incumbent Republican Attorney General Bill Schuette was prohibited from seeking a third term due to term limits and unsuccessfully ran for Governor of Michigan instead.
The Michigan GOP was unsuccessful in looking to win its 5th straight attorney general election.
Along with the offices of Lieutenant Governor and Secretary of State, the nominees for attorney general were chosen by party delegates at their respective party conventions.
Nessel defeated Leonard by 115,000 votes, becoming the first Democratic attorney general of Michigan since 2003, when Jennifer Granholm left office to become governor.
Despite losing the state, Leonard won 9 of 14 congressional districts, including two that elected Democrats.
