If that were all it was that would be bad enough but Trump isn't a good person. He never has been. The on-set of health and age degradation is just magnifying what he's always been... A destructive force without a care in the world. If he had stayed in the private sector he would have only had access to thousands of lives to destroy and that is horrendous. In his current position, it's millions upon millions. The country can't afford to indulge an aging, tired, old man who is also no good to his core.
It doesn't help things at all that his over-inflated ego burst its seams the moment he won his presidency.
It also doesn't help that his first priority is to please himself by appeasing himself.
It really doesn't help that as we all know, he's like a kid that just won a 10,000 piece jigsaw puzzle, has no idea how to go about putting it together and then proceeds to blame the folks that gave it to him for making him look bad because of his inability to solve a simple spacial acuity problem all while having a hissy fit over it.
He is obviously unfit for the job, and he's proving that every time he opens his mouth and every time he goes out on one of his Obama legacy hunting expeditions.
Whatever he does, whatever he says, it's for some selfish reason at the expense of the nation, and worst of all, he clearly doesn't give a shit what kind of damage he causes so long as he gets what he wants when he wants it.
This vicious cycle of appeasing himself and his base in order to keep himself happy and keeping his base by his side while ignoring the damage that gets done because of it has got to stop somehow.
It's just too bad that the Repubs aren't willing to do anything about it because loyalty, abortions, gay rights, "religious freedom" death panels and keeping their white nationalsits, supremacists, Nazis and various other flavors of bigots and racists placated and voting for their side of the aisle.
