 You can't get 80% of Americans to agree on the moon landing, but 80% of Americans agree that Joe Biden is too old to be president because it is more self-evident than either of the other two. Trump's lead over Biden in a two-person matchup is 48-42. It is the widest in general surveys dating to late 2021. Trump had just a two-point lead in February. The new survey began interviewing voters two days after the debate with Trump.
