Numbers are much more indicative of a 7-8 point national lead vs the double digits we are seeing.
Eh, not really. Trump won IA by 9.5% in 2016, IA would represent a 9.5% shift from 2016 (Biden +11 then), while Michigan, depending on the leaner model, is a 7-9% shift from 2016, which would be Biden +10 to +12 then. And then if you assume NV is really like Biden +9 given their polling errors, that would be a 7pt shift, for Biden +9 then.
So these essentially show a Biden +9-12 race nationally... which it is.
