Joe Biden confused Emmanuel Macron and François Mitterrand during a political rally on Sunday in Las Vegas. At 81, he is the oldest serving American president.
If he wins a second term, he will be 87 years old at the end of his presidency. Republicans frequently describe Biden as a senile old man, which has regularly led them to underestimate the Democratic president. At 77, Trump was the oldest president in American history in 2016, before his record was beaten by his rival. The two men are their respective parties' presumptive candidates in the upcoming presidential election.
