None of this has randomly come out of the woodwork, Togo. Trump's suitability for the presidency has been one of the major criticisms of him since he announced his candidacy. Even after he won the nomination, the line from his supporters was that he was leaving the character from the Primaries behind, and was now going to behave in a more presidential way. That never happened. It still hasn't. He is still behaving like a maniac - in fact his behaviour is escalating - after a year in office.
I'm no fan of Clinton, but she was absolutely right when she said "there is no other Donald Trump." That hysterical, thin-skinned, deceitful, narcissistic, deluded manchild we were introduced to in the primaries is still at it. But now he has nuclear weapons and the power of the U.S. executive. That is alarming, it is not funny, and it is not good for the world or for the USA. In fact it is precisely why the Americans saw fit to introduce the 25th amendment at all.
