U.S. Term Limits (USTL), based out of Washington, D.C., advocates for term limits at all levels of government. Since it was established in the early 1990s, USTL has assisted in enacting and defending term limits on state legislatures in 15 states as well as congressional term limits in 23 states. Unfortunately, the Supreme Court ruled 5-4 in U.S. Term Limits v. Thornton that states may not individually enact term limits for their members of Congress and the popular and hard-won congressional term limits never went into effect.
