Michigan Governor Gretchen Whitmer has thrown her support behind Haley Stevens in the state's upcoming Democratic Senate primary. Whitmer's endorsement comes as early voting begins, setting up a competitive race between Stevens and Abdul El-Sayed. Stevens is considered a moderate candidate, while El-Sayed represents a more progressive wing of the party. The primary is expected to be tight, with both candidates vying for the nomination to replace retiring Senator Debbie Stabenow. Whitmer's backing could give Stevens a significant boost in the race. Early voting has started, and the primary election is scheduled to take place later this year. The contest is seen as a key test of the Democratic Party's direction in Michigan.
