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

On November 5th, according to CNN, the "red mirage" refers to the phenomenon where the Republican Party initially leads on election night, but due to the counting of mail-in ballots, the Democratic Party takes the lead in the evening or a few days later. Trump has used this phenomenon to accuse election fraud, but it is actually due to mail-in voting and various state counting rules. In 2020, Biden's lead in Georgia did not become apparent until the early morning of November 6th, and in 2016, Hillary also experienced a similar shift in popular vote numbers but did not change the result. Each state must complete election certification by December 11, 2024 at the latest.
