Biden's leading by 14. Since we're about a month away, that's still enough time for the shock factor of Trump getting COVID to wear down which might bring national polling a bit closer but obviously Trump still has a lot of ground to make up.
Clinton was up like 4 points at this point in the election last year. And Trump won by like ~50k votes in that election by winning 3 or 4 battleground states. Not at any point was Trump this far off from her. IIRC Trump was consistently down 4-8 points and was down an average of 4 or so points leading up to election day.
