The Common Sense Party of California was a political party in the U.S. state of California. It was founded in 2019 under the chairmanship of Tom Campbell, and sought to acquire enough voter registrations to qualify as a state-recognized political party. As of March 2026, it had no media coverage, had apparently not progressed towards obtaining signatures to support state-recognition, and appeared to have no plans for participating in the 2026 midterm elections.
