Get on with it, Governor Snyder. Put an Emergency manager in charge of Detroit. You will never win the hearts or minds of the overwhelmingly Democratic city. But the longer you wait, the weaker you'll seem to everyone else. Just do it and get it over with.
Detroit is a classic case of the tail wagging the dog. Detroit leaders appear to think that Detroit is Michigan. That may have been the case at one point. It isn't anymore.
There are about 700,000 residents where there used to be 2,000,000. That's something in the area of seven percent of the population of the entire state. Detroit does not, or at least should not, have the clout it once had. The only real thing the city has going for it is political: the situation can be painted as David and Goliath, of Democrat against Republican; of plain old racism, even.
None of which is fair. Detroit got herself into her mess and is essentially refusing to get herself out of it. Someone else must. That someone is you, Governor Snyder. You wanted to be governor; you wanted to run the state like a business. So, do it. Maybe you won't be a hero to Detroit, but that was never going to happen anyway. Go on and be a hero to Michigan. Detroit may actually learn a lesson from that.
