National PV: Clinton +2.09
Oregon: Clinton +10.98 (8.87 points more Democratic than the nation as a whole)
Delaware: Clinton +11.38 (9.27 points more Democratic than the nation as a whole)
Ohio: Trump +8.08 (10.2 points more Republican than the nation as a whole)
Iowa: Trump +9.41 (11.5 points more Republican than the nation as a whole)
By the way, Virginia was also closer to the nation as a whole than Florida, Colorado closer than Wisconsin, and New Mexico closer than Georgia.
Oh, and, if you want to call Indiana competitive because of 2008 or whatever, New York was closer to the nation as a whole than Indiana!
If Ohio and Iowa are still swing states, than I guess Oregon and Delaware count too (and arguably even Connecticut, New Jersey, and Rhode Island).
You really can't make argument just off one election. Both Ohio and Iowa did move sharply last year, but neither one moved or trended Republican in the prior elections. Same with Indiana, it moved sharply Democratic in 2008, but really showed no trend prior. Colorado and Virginia on the other hand were already showing signs of becoming more Democratic before they flipped.
Now, that isn't to say the potential of those states from moving away from swing status isn't a possibility, it certainly is, especially if the Democrats don't improve with white working class voters, however one election cycle is simply not enough to tell.
