Biden's dementia has evolved past what was once morbidly amusing to the right and sad to everyone else. He, as the President of the United States, has become a risk to national security. There is now a very real chance that he, in a dementia-riddled fugue, could say something on the public stage that sparks a serious international incident.
Whether you're a Democrat or a Republican, a supporter or not, he simply has to go.
I expect him to say something or step out one day and drop his pants and pee. The WH staff must be petrified.
