A poll looking at national popular vote is not that meaningful. There are a lot of votes in blue states like NY and California.
One has to look at the battleground states and a bottoms up electoral count.
That may be true, but the electoral vote can only reverse up to a 3-4 point popular vote deficit. If Biden wins by 10 points in the popular vote, no way is Trump going be anywhere close to 270. It will be a rout. Guaranteed.
