There’s the one big question when it comes to 2024: Which presidential candidate is going to win in November?

Then there are lots and lots of other related questions.

“The Run-Up,” a weekly politics podcast from The Times, is trying to answer as many listener questions as we can — on the show, which you can subscribe to wherever you get your podcasts. And here.

What if something happens to Biden or Trump that disqualifies them? Like, I know this is morbid, but what if one of them dies?

Let’s start with President Biden and the Democrats.

We asked our colleague Reid Epstein, who is covering Biden’s re-election campaign, for insight into how the president and the Democratic Party are thinking about this question:

There is no Plan B. Joe Biden will be the Democratic nominee unless one of two things happens. Either he suffers a major health calamity between now and November, or Biden himself decides that he’s not going to run.

On the first point, you know, we all hope that the president remains in good health. He seems to be. He rides his bike. He rides the Peloton. He is a very healthy 81-year-old man.

There’s also no reason to believe that he’s going to wake up one day and decide this is not for him. Like, the man has wanted to be president of the United States for most of his adult life. He first started seriously considering running for president in 1984. He ran for president three times. He has already raised more than $200 million in this campaign for re-election. There’s no reason to think that he is going to change his mind.
