Rep. Sean Casten beats fellow House Democrat Marie Newman in Illinois primary

Between the lines: Newman previously represented the 3rd district until much of it was carved into the 6th.

• The 6th includes parts of the Chicago suburbs, like Downers Grove, but was remapped to take over parts of the 3rd in Southwestern Cook County.
• Carving Newman's 3rd district seemed to telegraph disrespect from Democratic party leaders in charge of the new map.

Of note: The race was extremely acrimonious.

• Newman faced allegations that she'd bribed a potential primary challenger with a job offer and is under investigation by the Office of Congressional Ethics, though Newman has denied any wrongdoing.

Newman came to Congress after beating one of the last anti-abortion Democrats, Rep. Dan Lipinski, in a primary challenge. In light of the Roe v. Wade decision, she had continued to highlight her record on abortion rights, though Casten has also been supportive of abortion rights.
