There are likely 4-5 serious Democrats getting into this Michigan Senate race. Mallory obviously being one of them. You'll also likely see Congresswoman Haley Stevens, Congresswoman Kristen McDonald-Rivet, and Dr. Abdul El-Sayed run. Attorney General Dana Nessel is rumored to be looking at running, but I think she's 50/50 at best, where as the other candidates more certain to run.
