Three more years to go…
I don’t think for a second that he will step down willingly. He’s proven that already, and all these jokes about a third term are not really jokes. He has now made a normal thing out of just talking about it, and that’s the first step.
Also, judging by how bad things have gone in just one year, I don’t think the world can stand three more years. I also have a feeling that something will happen before that. Either he goes stark raving mad and starts WW3, declaring martial law and cancelling all elections so he can stay in the White House until he rots, or maybe he becomes so visibly ill that Vance has to take over.
