PORTLAND -- The Oregon Secretary of State's office has begun to mail ballots for the May 15 primary.
The ballots mailed Friday in the state's vote-by-mail elections include races for attorney general, Congress and several seats in the Legislature.
Democratic voters will be choosing the state's attorney general in a contest between former U.S. Attorney Dwight Holton and former judge Ellen Rosenblum. Republicans did not field a candidate.
U.S. Rep. Peter DeFazio faces a challenge from the son of his 2010 opponent. Matthew Robinson says he's a conservative who's running as a Democrat to have a shot at defeating DeFazio.
A handful of incumbent state legislators are facing tough challenges from within their own parties, including Democratic Rep. Mike Schaufler of Happy Valley and Republican Sen. Chris Telfer of Bend.
