What actually happened
The contest to replace retiring Sen. Gary Peters was too close to call late Tuesday, but its significance was already clear. El-Sayed ran as a progressive challenger to the party’s Washington-aligned center; Stevens argued that Michigan needed a proven general-election candidate. More than $30 million in spending by AIPAC and affiliated groups for Stevens made outside money part of the argument, not just its backdrop. The eventual nominee faces Republican Mike Rogers in a race central to Senate control.
