“...this election is most certainly not about age...”
But it is about the obvious effects of age on the ability of her husband to do the job—any job really. Who, with any sense would hire anyone to do anything who routinely stares off into space with his mouth hanging open, or who has to be physically stopped from wandering off randomly?
Joe Biden has become an international laughingstock and by extension, so has the United States of America.
I wouldn't trust Joe to be the cashier at a food pantry where everything is given away for free.
