A professional statistician would notice the anomaly immediately. When over a dozen polls fail to approximate the outcome, it becomes obvious that the polls assumed an unbiased fair election. The polls don't take in to consideration widespread, industrial scale cheating by the Democrat/Communist machine.
The polls were not wrong.
What were the poll results for day-of voting states, vs those with lenient early voting?
In many of the races, when early voting started the Dems were in the lead, compounded by their ballot collection, and only at the end when a sizeable number of people had already voted did the Republicans take the lead.
Early voting undermines democracy, as does ballot harvesting - which is legal in one form or another in many states.
