 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. The new survey contains a range of signs Biden's political standing has weakened. At the same time, a small but growing number of Democrats are calling for him to withdraw as the party's nominee.
