Senator Bernie Sanders accurately predicted how the 2020 presidential election would play out during an appearance on The Tonight Show.

During his conversation with Jimmy Fallon, Sanders warned that mail-in ballots would become a major factor in how the election would play out. He explained that the delay in confirming ballot results, due to the high volume of mail-in ballots in certain states, would lead Trump to use his voter base’s distrust of voting by mail to circulate lies about being treated unfairly during the election.
