I think what concerns them is all the dims supporting him. Only a small number at the “kid’s” protest were kids, most were adults with long standing agenda groups. As long as those dims support him he does have power, whether we realize it or not. I think he is becoming a joke and when he is not useful to the dims any longer or becomes a liability they will take him out with the trash.
He has a strong tendency to go overboard and the Dems are going to want to dump him but they’ve invested too much in him to do it. They’re stuck with this brat until the mid-terms at least.
