Aelea Christofferson of Bend is challenging Congressman Walden.
She has not run for public office before and in her closing statemetns at the debate argued why she'd be a better choice.
"In the last year, I've made five thousand personal calls, knocked on hundreds of doors and when I talked with people they don't talk about the fine points of Obamacare. They are worried about putting food on the table, getting a job. I'm from Bend and I care deeply about Oregon and the health of our forests and people who don't have jobs."
Walden says he'll continue to do the work he's done for the last sixteen years.
"I commit to do everything I can get to America back on track. I'll continue to work on veterans healthcare issues like I pushed for clinics in Bend, Burns and LaGrande. I pushed the administration to tell the truth about the treatment of veterans. I'll stand up for ag."
The debate was held Sunday night at the Sunriver Resort.
