Republican Revolution (1994)
Republicans won the House and Senate for the first time since 1952, led by Newt Gingrich's Contract with America. The wave gave the GOP control of both chambers and a platform to confront President Bill Clinton.
Clinton shifted right, declaring in 1996 that "the era of big government is over."
Republicans held Congress until 2006, while Clinton won reelection in 1996.
Shows a midterm wave can hand the opposition Congress without ending the president's tenure.
