Abdul El-Sayed leads the Michigan Democratic Senate primary market at 67.5% implied probability, ahead of Haley Stevens at 25.9%, with Mallory McMorrow and others far behind. The August 4 contest for the open seat vacated by Gary Peters features a three-way race shaped by recent polling where El-Sayed edges or ties Stevens in multiple surveys, bolstered by substantial fundraising, the UAW endorsement, and appeal among younger and progressive voters. Stevens draws backing from party figures such as Jennifer Granholm and emphasizes electability against the likely Republican nominee. McMorrow remains viable through suburban support but trails in aggregates. A late-May debate underscored differences on foreign policy and party leadership, while high undecided shares leave room for shifts before primary voters decide.
