Overview

Mike Thompson is a Democratic member of the U.S. House of Representatives from California with a substantial voting record of 719 votes across a wide range of policy areas. His most active areas of legislative engagement are healthcare, budget and spending matters, agriculture, defense, and environmental or energy policy. On healthcare, Thompson has voted in favor of related legislation roughly two-thirds of the time, supporting measures like the Do No Harm in Medicaid Act and efforts to lower health care premiums. On budget matters, he has opposed more proposals than he has supported — voting against the fiscal year 2027 congressional budget and continuing appropriations measures — which is consistent with a member of the minority party opposing majority-crafted spending plans. His agriculture voting reflects his representation of a California district with significant farming interests, where he has supported agriculture appropriations and animal protection legislation. Thompson has shown strong support for defense and veterans' issues, voting in favor of 74% of defense-related measures, including veterans' care legislation. He has also supported all foreign policy measures that came to a vote. On environmental and energy policy, he opposed most measures — voting against roughly 69% — which may reflect opposition to proposals he viewed as insufficient or counterproductive to environmental goals. He has voted against most immigration-related measures, opposing 7 out of 8 bills in that category. Overall, Thompson's record paints a picture of a legislator engaged across many policy domains who votes consistently with his party while maintaining particular focus on healthcare, agriculture, and veterans' affairs.
