In the United States, members of the House of Representatives serve two-year unlimited terms and are up for re-election every even year. The House of Representatives makes up half of Congress and is comprised of 435 members.
During the 1990s, various states passed measures imposing term limits on representatives, until a 1995 Supreme Court case banned the practice. In addition, several Republican representatives, including South Carolina's Mick Mulvaney, proposed constitutional amendments to impose term limits in January 2015. Mulvaney proposed that representatives serve 12 years maximum and no longer. Term-limit proposals prove difficult to pass because it would require current members of Congress to limit their own terms.
