In 2012 Oregon was 8 points more Dem than the nation as a whole and Florida was 3 points more GOP.
In 2004 Oregon was 7 points more Dem than the national average and Florida 2 points more GOP.
No mystery here. This is what happens when the GOP wins a 3 point national victory.
Yea, people really need to understand the concept of PVI. Reagan won Massachusetts in 1984 by 3 points, when winning nationally by 18. MA was not a swing state since it was still 15 points more Democratic than the nation as a whole.
