Term-limited members
Under the Michigan Constitution, members of the state Senate are able to serve only two four-year terms, and members of the House of Representatives are limited to three two-year terms. Michigan has what are considered the toughest term-limits in the country. After the 2018 mid-term elections, nearly 70 percent of the state Senate and 20 percent of the state House will be forced to leave office because of term-limits. The following members are prevented by term-limits from seeking re-election to the Senate in 2018. This list does not include members that are eligible for re-election, but instead chose to seek other office or voluntarily to retire.
