i think maybe he’s trying to be a bit ‘more presidential’ since he’s in the lead.. this is a common tactic for persons in that position, the message being “I am the leader now so do not have to behave like a wild man to get media coverage, attention”..... and “you know you really do want a presidential kind of person as your president” —
the problem with this may be that America’s forgotten how a genuine American president behaves
Yes, I think your analysis is spot on.
