Maine and arguably Michigan should be dark blue.
Actually no this was Before Romney's Let Detriot Go Bankrupt statement that made him very unpopular in the midwest. Many pundits thought Romney would be stronger then McCain in the Rust Belt just weaker in the West vs Obama and in the South vs Hillary.
I have MO and NC flipping because IMO those states went where they are due to Palin being on the ticket(I think she cost the ticket NC and maybe IN but helped McCain win MO). I kept IN Dem though as I think Romney probably underperforms with religious right voters in that state(Turnout wise).
