Progressive candidate Abdul El-Sayed defeated AIPAC-backed Representative Haley Stevens in Michigan’s Democratic primary for the U.S. Senate on Tuesday, overcoming a significant fundraising and advertising disadvantage, according to NBC News. El-Sayed will now face Republican Mike Rogers, who won his party’s nomination unopposed after receiving an early endorsement from President Donald Trump. The victory marks another significant win for the Democratic Party’s progressive wing in this year’s primary season. Michigan is one of the states expected to determine which party controls the U.S. Senate after the November election. El-Sayed and Rogers are expected to compete in one of the country’s most closely watched Senate races.
