Biden senile during the debate?

This market will resolve to "Yes" if Joe Biden exhibits clear signs of senility consistently throughout the Presidential debate scheduled for June 27, 2024. Otherwise this market will resolve to "No". Isolated gaffes or occasional moments of confusion will not qualify. Clear signs of senility include but are not limited to persistent incoherence, confusion, inability to follow the debate format, or prolonged periods of non-responsiveness. For example if this market were about Biden's 2024 State of the Union Address, it would resolve to "No." The resolution source will be video footage of the debate. No updates or clarifications will be made to this market's rules.
