Yeah I thought that was a pretty WTF moment.
I dunno, at least at the moment I thought it was very positive. My mom is supporting Trump (or at least was; haven't spoken to her since Pussy-gate), and while trying to convince her own mom to support Trump, she used his kids as a reason which apparently seemed compelling at the time. To a wish-washy independent type that wants a leader they can relate to or understand on personal terms, raising successful/healthy/etc children is a great metric of a person's quality. (My grandmother ultimately refused to support Trump on the grounds that he's a misogynist, but still.)
