First of all, teams have changed names, changed cities, changed the name of their stadiums many, many times. In fact, the stadiums seem to be changing their names every year now as they get new sponsorship. It is commonplace.
Therefore, Trump is objecting to the reason they are changing the name, which we knew. He believes racism is bedrock American culture and he wants to preserve it. So do his followers.
But culture changes too. After all, there was a time when a man who wore flamboyant make-up and hair, as he does, would not be taken seriously as a politician. Our culture has changed. It changes all the time. And the kind of racism that casually dismisses the demands of racial minorities that they not be used as mascots is finally changing as well.
As for the new name, I like it. It has a connection with the city (there are two huge “Guardian” statues at the entrance to a big bridge) and the logo evokes the history of the team without demeaning anyone. In fact, I would go so far as to say that the native Americans who objected to this for many years are “guardians” of America by pushing so hard for our culture to recognize this sort of casual racism and change it.
Trump is a throwback who tickles America’s lizard brain every chance he gets. He knows his people.
