No, it is a sign that both terms occupy close relationships in the brain. I consistently fumble the name of my elder sister with the name of my eldest daughter and I know many people who have similar mixups.

Are you nitpicking that specific complaint? Or saying that Biden seems relatively okay?

Even the Democratic Party has given up on the far-fetched excuses. It’s time to surrender to the evidence. That example is just one out of dozens.

Laying out an argument (Biden mixing up names indicates he's senile) and having it disproven doesn't prove the case.

Biden is showing signs of decline, but the name-swapping thing was never (and still isn't) that. It's mental klutzery, nothing more. As the other person pointed out, it is /very/ common when two names are mentally-adjacent, to reach for the wrong one. My parents would call me by my brothers' names all the time, and I just did that with my own kids this morning.

Anyone who thinks that Biden got confused and thought he was in a press conference with Vladimir Putin (!!) is just spouting nonsense.

During the same event, he called his VP, Vice President Trump. Regardless of what you call it, it’s a bad sign similar to GW Bush’s constant gaffes.

I've been mixing up names for as long as I can remember. I'm not even 40. Of all the things to judge him on this rates pretty low on my list, especially since Biden has a bit of a history of "gaffes" like this.

That said, it's pretty obvious a lot of energy and fire that Biden previously had is no longer present. Or at least very inconsistently present.

the thing is. i dont remember a single fumbling of words by biden until he appeared back into the public recently. like he was great at speaking and decently quick witted.

the extreme change is worrisome. i mean is this him now? will it keep deteriorating? why would anyone think it wont. how much of a medical concern will be 1 year later. 2 3? this is what people are concerned with

Nah, he was known for this kind of thing. e.g. from 2013, "Best of the vice president's 'Bidenisms'" https://www.youtube.com/watch?v=LLcIMdHQvz8

2010, "Joe Biden, the vice-president who keeps putting his foot in it": https://www.theguardian.com/world/2010/jun/28/joe-biden-vice...

Those were just the top two results in Google for "biden vice president gaffe", limiting the date to before 2016.

I mean, it's probably gotten worse, although I can't really judge that. But it's certainly not a new thing. I'm not saying he's not too old and tired, I'm just saying that merely the mixing up of a name alone really isn't a sign of incompetence.
