He really needed not to go off on that tangent about immigrants eating cats. The old canard about the "undesirable other" eating animals contrary to prevailing social sensibilities has been around forever. In the town where I grew up, they claimed that, during WWII, an Italian restaurateur made his spaghetti sauce with cat meat. Nil novi sub soli.
And "Marxist" is a term with a fairly precise definition. Not shilling for hαɾɾιs, but she would have been well-advised to ask Trump "can you explain to all of us exactly what a Marxist is, and why you think I am one?".
She put a lot of airy platitudes out there, but Americans have never been ones to drill deep into the thinking of those whom they choose to lead them. This is a country where image is everything.
