With redistricting in 2022, the MI GOP should target the 5th and 9th to flip (although I assume the state may lose another seat or two, so that might be rendered moot).
MI will lose a CD, and the MI-09 is the one that should be gotten rid of (it should have been eliminated after the 2010 Census but Republicans chickened out). The heavily RAT parts of Macomb should be added to Conyers’s black-najority CD, and the white RAT parts of Oakland should be added to Lawrence’s black-majority CD (which already includes black parts of Oakland all the way up to Pontiac). The MI-07 in Jackson and Lenawee Counties, which already extends to Monroe County, should be stretched to take in the Downriver communities in southern Wayne (which voted for Trump). The MI-10 can be drawn from the GOP and marginal parts of Macomb plus the Grosse Pointes in Wayne plus as much of St. Clair County as needed to meet the required population. The MI-05 should be unpacked by sending Saginaw and Bay City to the MI-04 and substituting them with the Thumb counties (including the portion of St. Clair County that won’t be in MI-10), which would have given Trump a solid victory in 2016. Such map likely would give us 10 Republicans and just 3 Democrats.
