Peters’s chances of winning would be better if there wasn’t a fourth prominent Dem in the race—a white city official from Southfield who will likely do very well with the Jewish vote. But Peters still might get 30% and win, à la Cohen in TN-09.
There aren't many Jews or Irish/Polish Catholics left in Southfield. Almost all of the Jews moved to West Bloomfield and the Catholics out to Novi and beyond. Peters isn't Jewish, although he did represent a lot of the Jewish areas as a State Senator and Congresscritter.
I think Clarke will win, but I DO think John Conyers might be beat by Glenn Anderson in the neighboring district.
