There’s no way Detroit was going to vote for him to the point where it would have made a difference in the state.
Michigan has a heavy Muslim presence. I don’t know if they are registered to vote or not, but that may be one reason that obama would have an advantage in that state.
There is more to Michigan than just Detroit. Flint, Saginaw and Bay City are probably the the next 3 largest cities and all have been severely impacted by the recession here in Michigan.
As for Detroit tho, there are going to be less Detroit voters voting for HObama then voted for Clinton back in 1992........
