Jeff Merkley is a progressive Democrat who has emerged as one of the Senate's most vocal advocates for campaign finance reform, climate action, and voting rights. Before his 2008 Senate victory, he served as Speaker of the Oregon House of Representatives, where he helped pass the nation's first renewable energy standard requiring utilities to source power from clean energy. Known for his detailed policy work and willingness to use procedural tactics to advance his agenda, Merkley has become a leading voice on issues ranging from ending the Senate filibuster to opposing military interventions abroad. His blue-collar background as the son of a millwright has shaped his populist approach to economic policy and his focus on working-class concerns.
