Michigan Gov. Gretchen Whitmer endorsed Rep. Haley Stevens in the U.S. Senate primary, signaling establishment support. The race pits Stevens, viewed as centrist, against progressive Abdul El-Sayed ahead of the August 4 vote to replace retiring Senator Gary Peters. Stevens portrays experience and results-oriented leadership, while El-Sayed emphasizes coalition-building and progressive policy. The contest is seen as a clash within the Democratic Party as national networks and outside groups shape fundraising, with more than $52 million in super PAC spending through mid-July. Cook Political Report now flags the general-election race as a toss-up, underscoring Michigan’s battleground status. Debates are scheduled as the intra-party contest continues.
