In the interest of clarity, I don't think that Johnson quite qualifies as a hypocrite, since a hypocrite has to have something at least resembling principles, and Johnson appears to have nothing of the sort.
He appears to be an essentially complete, full-time toady, ready and willing and even eager to mouth whatever he thinks will please whoever he's desperate to please at the moment. I don't think he's ever had a thought or opinion of his own in his entire life.
Not that that's any better or anything - just an observation.
