Bonamici was endorsed on by the Oregonian, the state's largest paper. The paper's editorial board wrote another piece on Thursday encouraging voters to pick her. The ad touts the endorsement, along with nods from the other papers that are backing her.
Voting is well underway in the all-mail special election. Ballots are due on Jan. 31. Bonamici has received a boost over the airwaves from several national Democratic groups including the Democratic Congressional Campaign Committee, EMILY's List and Planned Parenthood, among others. By most indications, she's in prime position to win on Tuesday.
National Republicans, sensing that the race has largely remained in the hands of Democrats, have stayed squarely on the sidelines, save for a five-figure coordinated ad buy made by the National Republican Congressional Committee and the Cornilles campaign.
