According to the Pennsylvania Department of State, in the 2020 presidential election, Joe Biden received 3,458,229 votes, consisting of 1,995,720 mail-in ballots and 1,409,341 in-person votes on Election Day. In contrast, Donald Trump received 3,377,674 votes, consisting of 595,570 mail-in ballots and 2,731,230 votes on Election Day. In short, going into Election Day, Biden was ahead by 1,400,150 votes and went on to win Pennsylvania by 80,555 votes.

But a shift appears to be underway. The Pennsylvania Department of State reports that, as of Oct. 29, 2024, 849,849 ballots have been cast by registered Democrats, 468,067 by registered Republicans, and 155,909 by others. So to date, the Democrat mail-in ballot advantage over Republican stands at 381,782.

These numbers will change since mail-in ballots will be accepted up until 8 p.m. on Election Day…
