Cisneros advanced to the general election where N&P research revealed that Cisneros’ opponent repeatedly aligned herself with the Trump administration, material that contributed to the campaign’s award-winning digital and mail pieces. Cisneros ultimately won CA-39 by a margin of fewer than 8,000 votes. In total, over $37 million was spent during the race, making CA-39 the most expensive non-special election House race in U.S. history, and flipped Orange County from Red to Blue in an historic sweep for Democrats.
