What if he died? Covid killed him? Why would they try and hide that?
Maybe they are not sure they really want Kamala to be the pick.
IF they really did, Joe would have resigned as POTUS. Kamala would take the oath and immediately become POTUS.
The fact that Biden is still POTUS shows me that they are considering other candidates.
I imagine a lot of us are asking those questions. If Biden got Covid, is he alive? Is he in a coma? Is he being treated with Paxlovid, Remdesivir, or even - gasp - Ivermectin? Is he on a respirator? Who witnessed him sign his X post? His doctor is obligated to tell the country if Biden is truly functional.
