Michigan is a gerrymandered swing state that both parties have won in recent presidential elections. We won the governor’s race, gained 6 seats in the Michigan state Senate and 6 in the House. We also won Proposal 2, and the state will now have an independent redistricting commission.


How Redistricting Happened in Michigan

The following timeline is a high-level overview outlining major redistricting events and activity in the state of Michigan over the last 10 years.


Republicans won trifecta control of the state, meaning that Republicans won control of the governorship and both chambers of the state legislature.


Census data delivered to Michigan.

Republican-controlled legislature drew and approved new congressional and state legislative maps, both of which were challenged in court as gerrymandered maps.

Republican Governor Rick Snyder signed the new gerrymandered maps into law.


President Barack Obama won Michigan with 54% of the vote and Senator Debbie Stabenow won re-election with 59% of the vote.

Despite these Democratic victories, the new gerrymandered maps helped Republicans gain control of 64% of the congressional delegation and 54% of the state House.


Though Democrat Gary Peters won a U.S. Senate seat with 55% of the vote, the gerrymandered maps gave Republicans 71% of the state Senate.


The League of Women Voters of Michigan filed a federal lawsuit alleging the 2011 congressional and state legislative maps are unconstitutional partisan gerrymanders that discriminate against Democratic voters in order to advantage Republicans. The case is pending.


Voters elected Democrat Gretchen Whitmer to the governor's mansion, won a citizen-led initiative to reform the redistricting process, and won 6 seats in both the Michigan House and Senate.

Court Cases Impacting Michigan

Currently, there are two active court cases in Michigan. The League of Women Voters of Michigan and individual voters are suing Michigan’s Secretary of State, Ruth Johnson, challenging the state’s legislative and congressional maps as partisan gerrymanders. A trial is scheduled to begin early next year. Additionally, a Republican-backed group has sued to stop a citizen-led ballot measure that would reform Michigan’s redistricting process and take it out of the hands of politicians.
