Why is this a bad thing, specifically? Like, articulate reasons that this is bad.

To say the quiet part out loud, he simply isn’t charismatic enough to hold the President position. Common people don’t feel their future to be secure under his leadership. Look at GOP’s candidates meanwhile (DeSantis, Ramaswamy, Trump) - they are all populist if not anything else.

And like it or not, this perception matters. I can guarantee he’ll recieve less votes this time overall.

Populists should be fought because populism is a cancer. Biden is exceptionally charismatic, in my view. Significantly more so than most Presidential candidates not named Obama or Clinton.

Biden is exceptionally charismatic, in my view

I’m sorry, but that’s a delusional take. A fricking potato has more charisma than Biden.

It must be weird to be so wrong about what is cool or not.
Results will tell.
They really won’t. This will most definitely not be an election based on charisma, and then Biden will retire.
