All 38 seats in the Michigan Senate are up for election in 2022. Republicans currently have a 22-16 majority, and have controlled the senate since 1983. The Michigan state senate is up only in midterms, which usually favor Republicans more than presidential years. However, Republicans lost five seats in the bad year of 2018.
Michigan has a new state senate map, thanks to the Michigan's Independent Redistricting Commission. The commission drew lines that split many counties and split Grand Rapids, Ann Arbor, and the Lansing area to benefit Ds. The city of Detroit was split to reduce the number of black-majority districts from five to zero. The commission created several competitive districts.
Michigan Redistricting: State Senate Map Approved
All but seven current state senators are former state representatives. Two senators (LaSata, Theis) faced primary challengers endorsed by President Trump. Consider the districts in detail.
The election data for each district is the R candidates for President 2016 (P16), Attorney General 2018 (AG18), Governor 2018 (G18), and President 2020 (P20). (There was 1-5% of the vote for third party candidates in these races.)
This seat is 37% black and 17% Hispanic. It loses much of downriver and adds a chunk of Detroit. Erika Geiss lives here and will run for reelection. She defeated former state rep (14-20) Frank Liberati and four other Ds. Erik Soderquist will be the R nominee.
