This is a good observation. He wants to change his messaging because he sees the writing on the wall. Running around yelling about how shitty the country is, insulting his fellow countrymen, riding a wave of animosity towards minorities, etc. - this is the opposite of unifying. It's reinforcing the teams. He sees it's failing now, but he can't bring himself to actually attack Trump or the GOP. He has to lean into platitudes and empty shows of strength. At the end of the day, it makes him look like he's not angry enough at the US...probably because he's not. He doesn't have an affinity or an understanding of this country beyond narrow political gain, because he's never spent a day of his adult life outside of politics.
