Skeptical doesn't begin to describe my reaction to this poll.
EPIC/MRA is not the most reliable pollster ever, certainly. Still, I could see Romney winning Michigan by a point or two while losing nationally--at least, it wouldn't be totally unrealistic.
Yes it wouldn't be that unrealistic in a close election. However, unless North Carolina has shifted dramatically to the left and/ or Michigan dramatically to the right, I don't see Romney winning MI and loosing NC.
If ppp has Romney doing well in Wisconsin in their next poll, this one will carry more weight.
