You started it when you misrepresented the election results with this landslide nonsense. But OK, your other points are valid. The "traditional" swing states swung.
With less than two weeks to go, mainstream media suddenly (desperately?) quoted polls that suggested North Carolina was going to flip and could carry Harris to victory (pending results in your "traditional" swing states). In the end, it wasn't even close in NC and of course the swingers swung and the rest is history.
Apart from Carter and the first Obama term, the state has been red since Tricky Dicky. Not a snowball's chance in hell IMHO. That, to me, this colossal straw clutch was affirmation that the Democrats were going to be toast.
It will be interesting to see if the pollsters get a firmer handle on predictions going forward, but somehow, I doubt it.
