Biden stumbles during debate?

This market will resolve to "Yes" if Joe Biden stumbles at any point during the first in-person presidential debate in the 2024 election cycle, from his initial entrance, to when he exits the debate stage after the completion of the closing remarks. Otherwise, this market will resolve to "No". "Stumble" is defined as any incident where Biden loses his balance and has to catch himself, or falls to the ground. If no in-person debate happens before election day, this market will resolve to "No." The resolution source will be video footage of the debate.
