In a primary election race for Oregon's top law enforcement post, the candidate who pledged to protect medical marijuana patients scored a decisive victory over a rival who led a cannabis crackdown last year. Retired judge Ellen Rosenblum, strongly backed by proponents of liberalized marijuana laws, captured 63 percent of the vote in the Democratic primary for state attorney general. Because no Republicans sought their party's nomination for attorney general, the Democratic primary victor, Rosenblum, becomes the presumptive winner in November's general election, making her the first woman to claim that office.
