His so-called dementia is guilt. Biden has been a political kleptomaniac all his life. Him stealing the election was his pinnacle, and I truly believe he’s faking it both for sympathy and to save his behind when everything gets out in the open.
Now faking it is not something I thought of. If he is, he’s doing a bang up job because he’s clearly making himself out to be an absolute clown and the US with him.
