Might very well decide the election, they had been lagging and may need big days. One estimate I saw said that Philly alone needs 570k people to turn out today, they were only at 24 percent of their 2020 total coming into today. They got 115k of that by 8a. But Atlanta, Milwaukee, Detroit etc are in similar but less drastic situations. then of course the mail and ED turnout in NV, which is the biggest conundrum of the race. If Ralston is to be proven correct, they need a big few days there, mail will be a big part of the answer and it just had to be postmarked by today.
