Election night turnout in 2016 was 35% Democrat, 33% Republican and 32% Independent.
Assuming the turnout is identical in November then they are under sampling Independents by 8 points and oversampling Democrats by 5 points. This is the equivalent of a 3-4 point increase for Trump.
Therefore the actual poll result is +2-3 Biden which is identical to 2016 with Hilary. The electoral college will do the rest.
