Answered directly from the voter file with Voter Count
Michigan does not register voters by party. The breakdown below is modeled from recent primary ballot history.

Note: Michigan does not collect party affiliation at voter registration. These figures are modeled from L2 voter-file analysis of which primary ballot each voter pulled in recent cycles — they reflect primary participation, not party registration.
