It could be said for many states. My state of Tennessee was generally given credit for that, since we had lamentably gone (by pluralities) for Clinton in ‘92 and ‘96, but it was the repudiation of Gore (which he should’ve carried had he not gone full moonbat) that cost him the whole thing. It was just 10 years earlier when he ran for reelection to the Senate in 1990 he carried every single county in TN.
I would still not consider NH to be a swing state, as that was only one time in the modern era its vote mattered. It still remains at present, to the left of the overall national vote. Voting Dem 5 out of the past 6 elections tends to prove the point.
