Mike Thompson brings a unique blend of military service and wine country expertise to Congress, having served as an Army staff sergeant in Vietnam before becoming a vintner in California's Napa Valley. Known for his pragmatic approach to legislating, he has been a leading voice on gun violence prevention, chairing the House Gun Violence Prevention Task Force while maintaining his credentials as a hunter and Second Amendment supporter. Thompson has carved out a reputation as a moderate Democrat who works across the aisle, particularly on issues affecting rural and agricultural communities. His background in both the military and wine industry gives him a distinctive perspective on issues ranging from veterans' affairs to agricultural policy.
