Biden did one thing right, he proved the media has been lying about his mental competence. 😂😂

[dougsowell]

Where have these people been? Biden has been like this for at least 4yrs now.

[TheTCOLL]

Why is everyone acting so surprised. You can watch videos years ago of Biden barely able to speak. Last night wasn't even that bad by Biden standards.

[blitztim]

This is like telling grandma she can’t drive anymore.
It has to be done.

[ddellwo]

Shame on the US press for running cover for this train wreck over the last 3-1/2 years………🙄

[jasonwilson]

The derangement syndrome that is about to take place is going to be next level. And I'll have zero sympathy for the whiners this go-round, NONE.

[deadpool]

Everyone i watched the debate with (even Democrats) burst out laughing when Biden said there were fewer illegals crossing the border during his administration.

[melmingin]

The fact that people are shocked ??? Where have they been????

[johncasey]

So I guess all those Republican conspiracy theories about Joe's decline... ummmm... weren't in fact conspiracy theories.

[christdolphin]

it truly is shocking hearing these people saying they voted for biden because they didnt know how bad he was or they thought he was a "harmless" alternative to bad orange. incredible

[eagledefenseusa]

After that disastrous debate, Biden is done.

If Biden is reelected, the US is done!

[LCarrTXn]

All of these news outlets acting like his condition just suddenly appeared out of the blue.

[dawidnel]

oh c'mon all of you KNEW he was in major cognitive decline even in 2020. But you saddled your ride so giddy up.

[THEremiXFACTOR]

"how does he function during an eight hour work day?"
He hasn't done eight hours of work for years, come on.

[colbyroberts]

Where are all yall who called for the 25th amendment during Trumps term 🤷🏻‍♂️?

[kevink]

Its the same Biden we had last week. How clueless do you have to be to think Biden was "ok" up until last night?

[theresearcher]

If CNBC thinks he's done; if CNN thinks he's done; when even MSNBC thinks he's done - he's done.

[justme]

He won't quit. There's still a lot of money to make for the Biden family!

[Benjiist]

I used to work in a nursing home. Biden reminds me of that.

[thomasneal]

so, you are telling me, that as a functioning adult that has been alive for the last 3 years, it took you watching a debate to decide how you will vote.
