I don’t know about Wayne but Macomb and Oakland counties are seen as Romney’s home counties so I expect him to carry them.
I live in NW Oakland county but have family in Macomb. On recent visits I see Romney signs by something like 3 to 1 over 'bama in Macomb. Here in Oakland county it seems even higher, even in place like Southfield. I was mentioning to my wife the other day at how different it was compared to 2008. I have a slight hope that Romney might take Michigan.
