Biden lead in the Polls in 2020 thanks to independents. The polls had him at 335 to Trump's 203. Trump outperformed the Polls for a 2nd time (he won FL and NC regardless of polls) but still came up short at 232. Trump always outperforms the polls because people don't like to admit they'll vote for him.
Here's the final poll from 2020 that had Trump only getting 203 EVs... 29 less than he actually won.
