Biden sounds more and more like a grouchy old man every time he speaks. I'm guessing he's feeling the walls closing in on him, as even Democrats are souring on him and ready to dump him in 2024. He spent 32 years running for president and it's all fallen apart 18 months into office.
He gets 0 sympathy. He's a liar, a braggart, and a political opportunist of the lowest order. He'd throw his mother under the bus to retain power.
