After 20 years representing Oregon's 2nd Congressional district, Greg Walden is retiring. Walden is currently the only Republican in Oregon's congressional delegation, and members of his party are lining up to replace him. Earlier this month, we heard from some of the most prominent candidates running for Walden's seat in the Republican primary. Today, we’re adding one more: Justin Livingston. A real estate broker and Bend city councilor, Livingston announced his candidacy in late February, just two weeks before the filing deadline.
