So I'm thinking out loud here and this is probably going to be controversial ... But what if Harris took on a comedian (or an oaf) as communications director, to purposely do gaffes and create controversies, so maybe the for profit media might like her more. Basically a modern court jester.
I always thought things like Sean Spicer hiding in the bushes were very funny. A bit embarrassing for sure, but also pretty funny.
So it was "exposed" that the stupid man with a fragile ego is easy to manipulate ... I think that most people, who are not in the alternative fact news bubble, knew this for years already. People have been widely comparing him to a toddler since his first year as president, and those people include his own aides/appointees. It was so common that someone even wrote a book about it: https://press.uchicago.edu/ucp/books/book/chicago/T/bo51128380.html.
So imo "exposed" is the wrong word, something like "demonstrated yet again" would have been better.
