This BS is absolutely false and has already been addressed around here.
A "red mirage" was predicted what would very likely happen within Michigan, Pennsylvania and Wisconsin that election night in 2020.
"But the opposite could be true in northern battlegrounds such as Michigan, Pennsylvania and Wisconsin, where officials are not permitted to begin processing mail ballots until the day of the election (or, in Michigan’s case, the day before). In those states, a “red mirage” of Trump-heavy Election Day votes could linger until larger metro counties report huge tranches of early ballots later in the evening.” Link
Trump never had the lead in Arizona due to this state having counted the mail-in ballots before election day ballots. FOX News called Arizona for Biden at about 11:20 EST that night.
And it's absolutely false that Biden "got 20 million more votes than any other Dem candidate" during the last four presidential elections.
2012 Obama - 65,915,795 votes
2016 Clinton - 65,853,516 votes
2020 Biden -- 81,283,501 votes
2024 Harris - 75,009,338 votes
