The results of mail-in ballot counting may result in two stages: "red illusion" and "blue shift"

Odaily Planet Daily Report, according to CNN, the "red mirage" refers to the phenomenon where the Republican candidate is initially leading on election night, but then the Democratic candidate takes the lead due to the counting of mail-in ballots in the evening or in the following days. Trump had used this phenomenon to allege election fraud, but it was actually due to mail-in voting and the vote-counting rules in each state. In 2020, Biden's lead in Georgia did not become apparent until the early morning of November 6, and in 2016, Hillary Clinton also experienced a similar shift in the popular vote count, but it did not change the outcome. Each state must complete the election certification by December 11, 2024 at the latest.
