Both candidates were chosen on Saturday by more than 2,000 party members, who attended the convention at the Cobo Center in Detroit.
Wayne State University law professor, Jocelyn Benson, won the endorsement of the Democratic party by a 95% to 5% margin.
Benson was running against the current Detroit Clerk Janice Winfrey.
The MDP endorsement doesn’t guarantee that Leyton or Benson will be the ultimate nominee. That decision will come in August when the party meets for the state convention to officially pick their nominees.
