Despite his age (79) and a very relative popularity, Joe Biden has several times mentioned his intention to run for a second term on November 5, 2024. If, by chance, he materializes this vague promise and also had to prevail over a Republican candidate, for the moment still unknown, we can bet, without great risk of being denied, that he will not have the incredible leeway with which Ronald Reagan had started his second season at the White House: in November 1984, the former actor had won 49 of the 50 states with an 18-point lead in the popular vote.
