Two Republicans are battling to represent Washington's 4th congressional district -- the heart of conservative Washington, a place where being labeled a "vegan" could mean death to your campaign. In one corner sits Dan Newhouse: the incumbent, and one of ten Republicans to vote to impeach Donald Trump. In the other: a Trump-backed challenger, and former NASCAR driver, named Jerrod Sessler.In the newest episode of Sound Politics, hosts Scott Greenstone and Libby Denkmann check in with Spokesman Review reporter Orion Donovan Smith about how the race is shaping up - and what it could say about the future of the Republican party.Thank you to the supporters of KUOW, you help make this show possible!
