"In other words, had the 2020 election been conducted like every national election has been over the past two centuries, wherein the vast majority of voters cast ballots in-person rather than by mail, Donald Trump would have almost certainly been re-elected," the report said.
The study is called, "Who really won the 2020 election? Measuring the effect of mail-in ballot fraud in the Trump-Biden race for the White House," and was assembled by Jack McPherrin, Justin Haskins Donald Kendal, Christopher Talgo and James Taylor.
A summary of the results explains, "This paper examines the likely impact that fraudulent mail-in ballots cast for both Joe Biden and Donald Trump in the 2020 election could have had upon the overall electoral results, based upon recently unearthed evidence indicating widespread mail-in voter fraud indeed occurred in the 2020 election."
