Democratic Rep. Dan Lipinski of Illinois lost the Chicago-area seat he's held since 2005 to a progressive primary opponent mounting her second challenge from the left.
Marie Newman beat Lipinski, 47.1% to 44.8%, with 99% of precincts reporting. Newman's win marked a reversal of 2018 primary results, when she lost a primary challenge to Lipinski, one of the most conservative Democrats in Congress.
Lipinski has been a top target for liberals in 2020. Democratic presidential candidate Bernie Sanders, New York Rep. Alexandria Ocasio-Cortez, and a slew of progressive groups backed Newman. He's earned the Left's ire over the years for his opposition to abortion rights, for voting against Obamacare, and being against same-sex marriage long after it was a mainstream Democratic position.
Lipinski’s district, which includes Chicago's southwest side and surrounding suburbs, is a Democratic stronghold, all but guaranteeing a win for Newman in the general election in November.
