You do understand if the aggregate of polls is carrying too many sample errors, then yours and 538s mean is too low and the 12 and now 8 point lead is a statistical error and complete fiction ?
In actuality; I suspect the polling mean is around 3% too low and Trump is probably on 48% and Biden 49%. With an expectant swing of at least 1-3% more for trump going into the next week. I would put some money on it, but the bloody bookies seem to grasp probability and assumptions of bias in left leaning pollsters, more than you.
