Anyway, I'm not going to defend him as he is a political unknown, but to suggest that Granholm has any 'moral character' renders any political prism irrelevant in this instance.
MI has the worst economy of any state in the nation, Jennifer vetoes any and all pro-business measures, raises taxes across the board - they call them "fees" as they're not taxes you know.
Granny has substantially contributed to the economic cancer here, as she is a bona-fide, Canadian born, east coast educated socialist. She has (with various local union powers) done more to make this place look like New Jersey than desired. I'll suggest this purple electorate is going to veto that trend even if it means going with a newbie.
If you didn't know, DeVos' wife is the former head of the MI GOP. I've personally seen her introduce The President Of The United States on several occasions on the campaign trail.
