Michigan Dem senator throws support behind candidate to replace him in contentious primary

Retiring Sen. Gary Peters, D-Mich., has abandoned his neutrality in Michigan's high-stakes Democratic Senate primary, backing U.S. Rep. Haley Stevens as party leaders rally to stop progressive rival Abdul El-Sayed from winning the nomination.

Peters, who is retiring after two terms in the Senate, announced the endorsement Monday, saying Stevens "will be ready on day one to fight for Michigan." The move reverses his position from late May, when he told The Associated Press he planned to stay neutral in the Aug.
