Where does the President go from here?

'At trial, Mr. Biden would likely present himself to a jury, as he did during our interview of him, as a sympathetic, well-meaning, elderly man with a poor memory … It would be difficult to convince a jury that they should convict him-by then a former president well into his 80s of a serious felony that requires a mental state of willfulness.' – Special Counsel Robert Hur on why President Biden will not face criminal charges.

This is a massive blow to the President's credibility and reputation. There's very little denying that the arguments against Biden's age should be taken very seriously. If his pathway to re-election is so unclear following this report, what does he do? Resign? Continue into a defeat against Trump this November?
