Dems always overpoll in VA, Hilary overpolled in VA, too, that's why she went dark in VA, PA and Co; consequently, cost her PA. Biden will win by the same margin as Hilary, 50 to 46
2017 gubernatorial race and 2018 senate race did not overpoll Democrats. More like the opposite. Trends also need to be taken into account here. Joe Biden is a great fit for Virginia and he will rack up tons of votes in NoVa that gives him at least a high single digit win in the state overall. Donald Trump and his brand of Republican politics is toxic in these suburbs, as congressional and state house elections have shown. Uncle Joe will clobber him big time.
I didnt say Biden will lose VA, I said he will win by 4 and Trump is gonna close in all these battleground states when he starts campaigning, there hasnt been no debates, no ads whatsoever
