Midterm Election Law and Legal Definition

Midterm Election is a general election that does not coincide with a presidential election year, but occurs two years into the term of a president i.e. in the middle of a president's term in office, hence the name mid-term. While presidential elections are held every four years, general elections for other positions are held every two years. In a midterm election, some members of the US Senate, all members of the House of Representatives, and many state and local positions are voted on. Since US senators serve 6-year terms, their re-election campaigns are usually held during mid-term elections.
