The name of the national membership campaign to increase membership is GET CONNECTED! Working to Expand Term Limits.
This campaign is organized by U.S. Term Limits, an advocacy group dedicated to expanding term limits across the United States. They work to prevent states from repealing existing term limits and support efforts to institute term limits in states where they don't exist.
