Progressive Marie Newman beat eight-term incumbent Rep. Dan Lipinski (D-Illinois) in the U.S. House Democratic primary race on Tuesday. Her win indicated the importance that abortion plays in the Illinois' 3rd Congressional District. Newman's win was major win for the party's progressive wing. The election was a rematch – Newman, a businesswoman and activist, had previously lost to Lipinski, a business consultant and founder of an anti-bullying nonprofit, in a 2018 primary by two points. Newman, who dubbed herself the "real Democrat," beat Lipinksi 47.1 percent to 44.7 percent. Lipinski, one of the last anti-abortion Democrats on Capitol Hill, has often bucked his party. In 2008, he refused to endorse President Barack Obama. He voted against the 2010 Affordable Care Act and opposed same-sex marriage until the Supreme Court legalized it in 2015. I am bursting with pride and gratitude for the amazing coalition that helped bring about much needed change in our district. We are going to work together to lower health care costs, to fight climate change, and to build an economy that works for everyone. #NewDayInIL03 #IL03 — Marie Newman (@Marie4Congress) March 18, 2020 The progressive group Justice Democrats had backed Newman's bid. It is the same group that assisted high-profile freshman Rep. Alexandria Ocasio-Cortez, in defeating the long-serving Congressman Joe Crowley in the 2018 cycle. Ocasio-Cortez had endorsed Newman in the race, alongside Chicago Mayor Lori Lightfoot. The Justice Democrats' executive director Alexandra Rojas wrote on Twitter that Newman's win over Lipinski signaled that, "if you do not like a Democrat, you will be held accountable." This sends a message to every Democratic incumbent that if you don’t vote like a Democrat, you will be held accountable. https://t.co/QX2mOKFmU1 — Alexandra Rojas (@alexandrasiera) March 18, 2020 Congratulations to @Marie4Congress in #IL03 This isn’t just a loss for one incumbent. It’s a defeat for machine politics and big corporate donors who want to stop our movement for Medicare for All, a Green New Deal, and reproductive rights. pic.twitter.com/yP30ZeZwl4 — Justice Democrats (@justicedems) March 18, 2020 Lipinski had represented Illinois' 3rd Congressional District since 2005.
