Angus King stands as one of the Senate's few independents, caucusing with Democrats while maintaining his reputation as a pragmatic centrist who often seeks bipartisan solutions. The former two-term Maine governor built his political brand on independence from party orthodoxy, frequently breaking with both sides on key issues while championing energy policy and national security matters. Before entering politics, King worked as a lawyer and entrepreneur, founding an energy company that reflected his long-standing interest in renewable energy and Maine's economic development. His folksy, approachable style and willingness to engage across the aisle have made him a distinctive voice in an increasingly polarized Senate.
