Marie Gluesenkamp Perez represents a competitive swing district in southwestern Washington as one of the most moderate Democrats in Congress and co-chair of the Blue Dog Coalition. The auto shop owner and mother won a surprising upset victory in 2022 in a traditionally Republican-leaning district, flipping a seat that many considered safely red. At 35, she brings a blue-collar perspective to Congress, often breaking with her party on issues while maintaining strong local roots in her rural community.
