Resolves YES if Biden or his campaign officially announces he is withdrawing or suspending his campaign for 2024 US President, by the end of the last day of the Democratic National Convention (scheduled for August 22). Any circumstances that force his withdrawal (e.g. death) count as YES as well. Otherwise resolves NO.
Note that this is very close but not exactly the same as https://manifold.markets/NathanpmYoung/will-biden-be-the-2024-democratic-n because of things like: Biden could theoretically suspend and then unsuspend the campaign (counts as YES here because he dropped out, but then he could still end up being the nominee). Or theoretically Biden could announce he's withdrawing but he could still get the votes from the delegates. Also this will resolve sooner if he drops out.
