Two scenarios:
1- If a US President is removed or dies BEFORE he/she has completed 2 years of the term, the next 2 years are considered a term for the person assuming the office and that person can be elected only one other time........if a US President completes 2 years of the term, the person assuming the office is completing the term and can be elected two other times. January 21, 2023 is the first day of the 3rd year.
2 - Fraud vitiates everything. Since more than 2 people were running for president in 2020, all participants were frauded, which means, another election should be held.
