Trump is demonstrability a child in a dehydrated tangerine for a body. He doesnt have the intellect to plan and execute from conception to reality, becoming the president of the united states. Even worse than that, even if he did, hes a lazy cunt and would never bother to do shit. That enough shows me everything about trump is orchestrated for him, just like everything else in his life, minus the ego. So whether he is fit to be in office or not is irrelevant because the only way to get him out of office is to show evidence for impeachment, if its so clear-cut as people say the investigation would already be over and not currently on-going as is.
Other than that being shit at your job isnt necessarily something that gets you demoted as president. It is my dream people would stop losing their shit over irrelevant questions and deal with these issues like emotionally mature adults and vote how they see fit when the time comes.
