Progressive Democrat Dr. Abdul El-Sayed won Michigan’s Democratic primary for the US Senate early Wednesday, narrowly defeating moderate US Rep. Haley Stevens in a race that will send him into a closely watched general election against former Rep. Mike Rogers, a Republican, with control of the Senate potentially at stake. El-Sayed secured the nomination by less than a percentage point, a considerably tighter margin than pre-election polling had indicated. His victory represents a major breakthrough for the Democratic Party’s progressive wing in the battleground state after his unsuccessful 2018 gubernatorial bid, when he lost the Democratic primary to now-Gov. Former Vice President and presidential candidate Kamala Harris urged Democrats to unite behind El-Sayed, sending a fundraising email asking supporters to donate. The Michigan Senate contest is expected to become one of the country’s most competitive races, with El-Sayed and Rogers competing for a seat that could influence which party controls the U.S. Senate after the November election.
