WHAT IS A MID TERM ELECTION
It is the election for senators and representatives that takes place between presidential elections. Some senators and some representatives run for re-election at the same time the presidential race is being decided. The terms of senator and representative, however, are staggered so not everyone is up for re-election at the same time. The election taking place next Tuesday, November 7, 2006, is a mid-term election because the president was re-elected just two years ago and is not up for election this year.
Good answer except that the terms of representatives are not staggered; all reps run for election/reelection every 2 years.
