Democrat Josh Riley will unseat Republican Rep. Marc Molinaro in New York’s 19th Congressional District, CNN projects, securing a critical swing seat for Democrats as they try to win a House majority.

The rematch between Molinaro and Riley looked like one of the closest contests in the country heading into Election Day, with Democrats in particular viewing the district as a must-win, CNN notes.

Riley, a former counsel on the Senate Judiciary Committee, hammered Molinaro throughout the campaign over his votes against codifying Roe v. Wade.
