The same time as it takes the republicans to say that Mitch McConnell is dead. Any minutes now

I'll believe he's dead when the price for alcohol and fireworks suddenly doubles

I'm guessing one of his children is placing suspicious bets on kalshi within minutes

Infinite because he does not emit light.

It will be near instantaneous, like a great disturbance in The Force - as if millions of voices suddenly cried out "we're free from terror, he's finally been silenced!"

Probably quickly, though this administration is known for shenanigans.

I have a standing bet that he dies during one of his naps on camera.

Throughout whatever is happening all the people around him will look upset by the smell and grow more and more concerned, but much like how nobody wanted to check if Stalin was really dead, they keep the cameras rolling until they can quietly check.

We’ll have all seen him dead well before the announcement.

How do you know it hasn't already happened?
