Republicans have flipped Oregon’s pivotal 5th District seat in Congress, with Republican Lori Chavez-DeRemer defeating Democrat Jamie McLeod-Skinner in a race flooded with out-of-state GOP spending. That means Republicans will at least double their number of Oregon’s seats in the U.S. House, with Chavez-DeRemer, the former mayor of Happy Valley, joining Republican Cliff Bentz, who represents the heavily Republican 2nd District that covers most of eastern Oregon.
