I don't think they will impeach him. They won't have to. There is more and more evidence that he is suffering from dementia. Even if that isn't true, over 9% inflation and shortages of essentials will not help his approval ratings.
I wish we had had Yang, Bernie, or Warren as the Dem candidate instead of Biden.
Even when he was younger and fully functioning, Biden was not known for his competence. President Obama said at one point that you could rely on him to f*ck things up.
If he has dementia (which I think he does) he will not make it to another 2 years regardless of what the GOP does.
