Not sure about that but I do know that Trump overperformed his 2016 percentages in every swing state and was over 50% in two of them, NC & FL.
Biden is under 50% in all swing states.
More interesting data points.
I really think it’s important to find out this information..... If trump’s lead in PA in 2016 never exceeded 100000 and he increased that by close to 800%, It makes the idea that Biden had this late surge in the middle of the night that much more suspect
