I expect Romney to be competitive in MN and NM but if I were running "Purple Poll" I'd take those states off the list. They are swing-y states but they will not decide the election.
How would you define MN as swingy?
It has the longest streak of voting Democratic in the country and was only close when Ralph Nader siphoned votes from Al Gore's left.
Minnesota was also considered a deadheat in 2004, and also was closer than Wisconsin, Michigan, and Pennsylvania in 2008. That being said, I don't think it'll be too closeit won't be too close this time around.
IIRC Minnesota was only close (relatively speaking) because Obama was basically non existent in the Minneapolis St Paul media market especially compared to McCain.
