What happens if Biden dies before the next inauguration (see inside)?

amendment 20, section 3. the vice president-elect gets inaugurated

I think it'd also count as a full term in office so far as the rule against running more than twice goes. So you could run for reelection, but that isn't a "one werid trick" to getting three terms in office.
- it's a two-term limit with a 10-year maximum. if the vice president gets called up 23 months before the end of the president's term, they could potentially successfully serve two and a half full terms
- One weird trick for getting the FDR special: assassinate your running mate before your first term starts
And the 25th regarding death and disability, depending on when he kicks off. For those interested in learning more:

I'm just going to point out that trump is only 3 years younger, and has far more risk factors for heart attack and strokes.

Why does everyone seem to think Biden is the one who will die first.

Because if Trump dies then we have a lot less to worry about
- We have less immediate issues on that front, but we still got some work to do
Why does everyone seem to think Biden is the one who will die first.
because we recently saw them in televised debate and one of them looked in significantly worse shape than the other.
- Just goes to show how little people know about how people die.
- My grandmother lived with dementia for 20 years before dying at 101.
- I did not take him as in worst shape. I saw a person who couldn't believe the bullshit being said by a narcissistic moron. I would have the same look at my face in disbelief if I had to debate with someone that I thought still asked for crayons at a restaurant.
TBH because of his physical presentation at the debate. Yeah, it’s short-sighted, but welcome to the public thought process. Whatever is churned thru the latest 15 minute media cycle seems to be what they believe.
Doesn’t matter if he had a cold and was dosed up on NyQuil or whatever; his voice was weak, he stumbled over making coherent sentence multiple times, and he just had a blank, open-mouthed stare when between questions. I’ve had shitty colds and been drugged up with cold meds and I know that feel of being sore, exhausted, hoarse, and disconnected. You just want to go have a lie-down, not a public debate against a raging, insulting, narcissistic asshole. But it takes someone willing to understand all that and give Biden the benefit of the doubt.
There are far too many that start from the “old” part and just attribute everything possible to that which they find disagreeable.
- his voice was weak, he stumbled over making coherent sentence multiple times, and he just had a blank, open-mouthed stare when between questions.
  And apparently that matters more than the blatant lies and non-answers coming from the other side. Gotta say, Americans do seem significantly dumber than the average world citizen.
- Did he have a cold, and cold medicine? I've not heard those things.
Let's look at oldest mainline Presidential nominees in history:
Biden - 2024 (81)
Trump - 2024 (78)
Biden - 2020 (77)
Trump - 2020 (74)
Reagan - 1984 (73)
Trump - 2016 (70)
Reagan - 1980 (69)
Next President who was elected was William Henry Harrison, but we're getting "young" enough there may be unelected nominees I'm not aware of.
Also: fun fact. Jimmy Carter's post-presidency lifespan has been over 43 years so far, while Teddy Roosevelt was only 42 when elected Predident.
There are so many more eyecatching things wrong with Trump, so his age never gets brought up. Biden mostly just has his age and the Israel situation, so those are the two things you hear about the most.
Because Trump now thinks he has full immunity to assassinate his political rivals
- Let's not hope both take a stroll on 5th avenue at the same time.
There's 100 year olds that are more competent than Biden.
Because he's so much more elderly than trump.
- The right all week accused Biden of taking performance enhancing stimulants. I'm unclear where they got that information, until you remember one thing. When the GOP accuses the left of something, it usually comes out later that its because thats what THEY feel guilty about themselves doing.

Also consider what happens if Trump dies at any of these stages - he's almost the same age so all else being equal he's almost as likely to die during the same period

One definitely seemed more likely to die than the other 😂
I bet they already have the conspiracy theories prepped for when Trump dies. It would be interesting for someone to make a Reddit post asking for MAGA to share their theories that someone is trying to terminate Trump, so that when he eventually passes from natural causes, we could pull that up as relevant info to see why no one did anything beforehand to prevent the attempt or if the conspiracy that emerges wasn't stated before it happened.
Bonus round with the upcoming (small) bird flu epidemic:
What if both die days before the election due to a sudden illness?
- I guess it’s Harris vs whoever Trumps running mate becomes

There's actually a novel that describes the process and it actually depends on when it happens.

If Biden wins the election, but dies before the electoral college votes, it's a free-for-all. The electoral college can vote for whoever they want.

If he dies AFTER the EC vote, but before it's certified, there's a different set of problems.

If he dies after the vote and the certification, the VP becomes President.

If Biden wins the election, but dies before the electoral college votes, it’s a free-for-all. The electoral college can vote for whoever they want.
This is unclear. Some states have laws that say that electors must vote for who they're pledged to vote for.
- But there's no enforcement.

The Vice President-Elect is sworn in instead. This is covered by section 3 of the 20th amendment.

Section 3.

If, at the time fixed for the beginning of the term of the President, the President-elect shall have died, the Vice President-elect shall become President. If a President shall not have been chosen before the time fixed for the beginning of his term, or if the President-elect shall have failed to qualify, then the Vice President-elect shall act as President until a President shall have qualified; and the Congress may by law provide for the case wherein neither a President-elect nor a Vice President-elect shall have qualified, declaring who shall then act as President, or the manner in which one who is to act shall be selected, and such person shall act accordingly until a President or Vice President shall have qualified.

I wonder if anyone is taking bets on who will croak first? Like Vegas for example

I got $20 on trump dies first. All that McDonalds is going to add up.
- plus, he's definitely taking an adhd stimulant since Fox News et al. has been accusing Biden of doing that.
- Evil motherfuckers tend to live forever, unfortunately. It's the pure concentrated hate that sustains them.

jimmy carter will out live both mark my words

As long as he stays away from rabbits!

President Harris and Vice President Jefferies

Anything else means instant constitutional crisis, but at the same time, we'll be able hear the explosions from space as right winger minds absorb that circumstance has brought about the first female president and also the first PoC President Vice President team.

If Kamala was good at trolling she'd not nominate any white people to the cabinet so we can all enjoy fox pundits trying to find the magic combination of words that let them be mad about an all PoC cabinet without it being racist, but I'm pretty sure she's at least going to keep Buttigieg on as Transit Czar since he's been going at least hard enough to get HSR moving finally between LA and Vegas.

I would start watching Fox News just to get the petty sense of revenge from watching them shit bricks over an all PoC cabinet.
Vice President Jefferies
It doesn't work that way. First of all, Mike Johnson is the Speaker, and is next in line for the Presidency after the VP, not Jeffries. But that entire list is strictly to see who would be President if the office were suddenly vacant. The House Speaker would only take over if there is a Presidential vacancy while the office of VP is also vacant.
Should Harris becomes President due to Biden leaving office early, the office of VP would become vacant and remain so until President Harris picks a replacement, and that replacement is ratified by both houses of Congress. Sadly, in today's political climate that is not a guarantee.
- I was talking since Jefferies would likely be Speaker in the scenario where Biden won the election but then died of old age.

See inside what? Did you link to anything?

As I see it, key deadlines are:

The party conventions, where each parties nominee will be formalized. (But recall that the actual Democratic Nomination will be done before the convention, to meet some State deadlines).
The election itself, where voters choose which slate of electors cast EC votes.
The electoral college election that really matters.
The counting of the EC Votes
the inauguration

Once the nominations are formalized, they probably can't be undone, since there are State deadlines involved.

But always remember that people are not voting for the candidates themselves, but for a slate of electors. And while the expectation is for these electors to vote for the ticket they were pledged to, if one candidate is subject to God's Almighty Recall Vote, they appear to have the discretion to file votes differently.

Once the EC votes are cast, though, there would probably be no choice but to accept them. (Congress recently revamped the counting process to eliminate some of the shenanigans that happened last time). I expect that if either one croaks after that, they would probably just inaugurate the VP on the ticket directly.

(Edited to add: states may be able to change EC votes after the December EC election. That date is based on a "safe harbor" deadline which makes EC votes harder to challenge. So, if the winning candidate bites it on Christmas Day there's probably a way for State Legislatures to certify new EC votes before Congress counts them Jan 6, but we should expect a challenge to that.)

(It would suck if Trump won, and Biden croaked on Jan 19th. We might have our first female President, for one day.)

Additional question. If the Vice President takes over and becomes President, do they finish the full term or are they just interim president until a new election can take place?

They finish the current term and appoint a new VP. The election calendar doesn't change
- Thanks.
- So the new President just picks whomever they want to be Vice President? It doesn't automatically become the Speaker of the House? Also, is there a confirmation process that the VP nominee has to complete similar to Supreme Court Justices?

They can literally keep a dead guy on the ballot. Then the vice president would take over immediately upon inauguration.
The Democratic Party could quickly pick a different candidate and have that person run and beyond the ballot.

There is a procedure for this. To simplify the answer, Kamala Harris will become President on inauguration day in any of your listed scenarios, since she's the current VP/VP-elect.

It's theoretically possible that if Biden drops dead today, that the DNC could manage to pivot to a new contender, but there are two significant problems with that:

It's suuuper late in the process. They already called the primaries for Biden, so he has the delegates. If he dies, they go to his VP, so it would be up to Harris to give them to someone else at that point if anybody else were to be selected (essentially dropping out of the race herself). This is a bad move because giving delegates to someone who didn't even primary will seem undemocratic, coronating somebody that the people did not even endorse for the ticket.
Replacing Biden with someone else doesn't give them much time to campaign. A big part of the election cycle is traveling to swing states to convince those people to vote for you. It's not that those people are suddenly going to go vote for the other guy (Trump, in this case), but they're far more likely to stay home because they won't be energized for this newcomer who didn't have enough time to court their votes, or to convince them to turn out for their policies/platform rather than be apathetic about the outcome of the election.

I'm surprised the CIA doesn't know the answer to this, so they have to come to lemmy to ask

Some times you want somebody to double check your work before you turn it in

Watch White House Down (2013)

Harris goes from VP to P. Which I really think would be a bigger disaster.
