This is the story. Not quite as medically invasive as it sounds: re-enacting the debates with a male actor playing Clinton and a female actor playing Trump. Everyone expected a female Trump to be unbearable - but it turns out s/he's a really appealing character, whereas a male Clinton is even more unlikeable.
It's an interesting example of upending one's expectations. I would also say it's a pretty good rebuke to the idea that people don't take to strong women in politics. A certain confident, forthright style seems to go down well, as least in debates. As if Margaret Thatcher's performances at the dispatch box did not already prove that.
