Michigan is a state that would naturally be heavily outraged by recent obama administration moves on homosexuality and immigration.
Michigan isn't particularly hostile to gay rights. The Republican state legislature is intent more on turning Michigan into a Duty-to-Starve ("Right-to-Work") state in all but name, but that can be turned around fast. Immigration is one of the possible solutions to the state's sagging real estate values. I see no reason to believe that Michigan would be going against nationwide trends on immigration or gay rights.
I'd love to see PPP, Marist, or Quinnipiac do a poll not only on Presidential support but also on gay rights and immigration in Michigan.
