Yes and I consider Manning and Davidson equally unfit to be PM, especially if they took their persona from a televised comedy into the job during a crisis, as Johnson has done. If they are the people you're comparing him to it speaks volumes IMHO.
Rather than a gloat it was vindication of my initial reaction to his appaling joke, which would have some complaining that the PC brigade won't let you do jokes any more, but after a rethink it does drag me down to his level. On this occasion I'm going to let it stand though.
