Many third party voters, assumed that, if elected, Trump would act presidential and not be the embarrassment he was on the campaign trail. They figured his sexist comments, making fun of the disabled and minorities, kissing Putin's ass, and behaving in a "grab 'em by the pussy" manner would be replaced with a presidential respectability.
Sadly, a shift to 'dignified" and 'respectable" never happened. Many third party voters (not referring to you, Ralphy) guessed wrong. Trump continues to be an utter disgrace. So, yes, Trump
should be more responsible, but that is not in his DNA.
His DNA is pure "Uhh, I don’t know what I said. Uhh, I don’t remember" and "Grab 'em by the pussy"...
