This is relevant:
A year before the election he is in the area of 44% approval which on its own gives him a 50% chance of winning re-election. But that could be very close to his ceiling. The severe negative ratings must go down before he has a strong chance at re-election. His likely opponent simply is badly known in southeastern Michigan where the votes are. The unions will never forgive Rick Snyder for his promotion of Duty to Starve legislation and feminists will never forgive him for a harsh anti-abortion law.
...Barack Obama having only 39% approval in Michigan... ha, ha, ha!
