 Leah Pfeiffer says she won't run in a crowded Democratic primary to replace representative Rick Nolan. Pfeiffer was among the first candidates in the 8th congressional district race, challenging Nolan for the party nomination before the third term lawmaker decided to retire. Pfeiffer is a former counterterrorism analyst who ran primarily on environmental issues like opposing copper mining projects on the Iron Range. She had been considered a frontrunner in the race but announced Wednesday she would not run in a primary. Northeastern Minnesota Democrats held the convention over the weekend but failed to endorse a candidate after 10 ballots. Her decision may be welcome news to some party leaders who worried that a five-way Democratic primary would hobble Democrats in a competitive election. Republican Pete Stauber is running unopposed.
