The Age Factor: Biden's Second Term and Winning in 2024.

Despite concerns over President Biden's age, polling and academic research suggest that it may matter less to voters than their responses to polls indicate. Americans often express concern about aging leaders, but that hasn’t stopped them from voting for older candidates. In a polarized era, party loyalty is far likelier to determine voters’ choice. Mr. Biden’s age may ultimately matter most to swing voters who are open to backing either party, giving them outsize clout to pick the winner.
