Contentious Democratic Senate Primary in Michigan Signals Party Tensions

One of the year’s most significant primary battles is unfolding in Michigan. Two Democratic Senate candidates with contrasting views are in a heated race, reflecting the party’s internal challenges. Dr. Abdul El-Sayed, a progressive former public health official, competes against Representative Haley Stevens, a centrist who has backing from party leaders. The outcome will determine who defends the retiring Senator Gary Peters’ seat in a key battleground state affecting Senate control.

Alongside Michigan, four other states—Kansas, Virginia, Washington, and Missouri—are holding primaries on Tuesday.

Tensions Between Candidates

Dr. El-Sayed supports universal healthcare and critiques U.S. military aid to Israel. He plans to spend Tuesday campaigning in Detroit. Ms. Stevens, promoting herself as a bipartisan antidote to political dysfunction, is on the move from Western Michigan to Detroit. She is also a strong ally of Israel.

The campaign has been marked by personal attacks. Dr. El-Sayed labeled Ms. Stevens the “least capable candidate in America” due to her support from the American Israel Public Affairs Committee, which spent heavily in her favor. Ms. Stevens countered on social media, accusing him of blaming his problems on Jewish Americans.

The winner will face former Representative Mike Rogers, who is unopposed for the Republican nomination.

Additional Michigan Battles

In Detroit, voters are deciding whether to support Representative Shri Thanedar or challenger State Representative Donavan McKinney, a democratic socialist. Meanwhile, a swing congressional district encompassing Lansing is witnessing a contest among two centrist Democrats and a progressive, all vying to challenge Representative Tom Barrett, a vulnerable Republican distancing himself from President Trump.

What Else to Watch

• A Missouri Comeback? Former Representative Cori Bush seeks to reclaim the St. Louis-area seat she lost to Wesley Bell, who benefited from pro-Israel groups’ spending.
• Heavy AIPAC-tied Spending: Over $60 million in outside spending has supported Ms. Stevens, with more than half coming from AIPAC’s super PAC, making funding a core issue in the contest.
• Control in Kansas: As Governor Laura Kelly steps down due to term limits, Democrats and Republicans are vying to succeed her. State Senator Ty Masterson, endorsed by Mr. Trump, is in the Republican primary.
• A Pacific Primary Fight: Representative Marie Gluesenkamp Perez, a centrist Democrat, is fending off challengers in her southwestern Washington State district.

The Broader Implications

The Michigan race, fraught with tensions over issues like Israel and electability, is the costliest and most acrimonious Democratic Senate primary. The contest’s outcome could influence the Senate’s control in November and impact the Democratic Party’s future direction. Recent polls indicate Dr. El-Sayed, a progressive, may have an edge over Ms. Stevens, who has significant establishment support. This race is pivotal, offering a chance for progressive Democrats to claim a key victory in the primary season. Centrists, however, view it as a chance to frame a winning strategy for November.
