Michigan's Democratic primary for a U.S. Senate seat remained undecided late Tuesday night, with progressive candidate Abdul El-Sayed — a former public health official and son of Egyptian immigrants — holding a slim lead over Congresswoman Haley Stevens. The closely watched race will determine who faces Republican Mike Rogers in November, a contest seen as pivotal to Democrats' hopes of recapturing control of the Senate. El-Sayed campaigned on universal healthcare and campaign finance reform, while Stevens positioned herself as a pragmatic moderate backed by tens of millions in outside spending, including from pro-Israel group AIPAC. Elsewhere in Tuesday's primaries, Democratic Representative Marie Gluesenkamp Perez advanced through Washington state's all-party primary to face Republican John Braun in November, and in Missouri, incumbent Democratic congressman Wesley Bell defeated progressive former representative Cori Bush in their second consecutive matchup, with the race seen as a setback for pro-Palestinian candidates who have notched several recent primary upsets.
