The "listen about Trudeau" has been widely misunderstood.

I believe that Mulroney was referring to the fact that one/The Conservative party  should not underestimate the fact that a youthful, media savvy, and attractive leader will have many natural advantages right out of the gate, and regardless of what comes out of his mouth.

Mulroney himself was the beneficiary of this 30 years ago (attractive young family, etc - what is not to like)

And today, in the USA look at all the "goodness' that is projected on Trumps' "highly influential" daughter, even though there have been several analysis that have correctly pointed out that people have projected all sorts of things on her, owing to her attractiveness ("someone that pretty can't be greedy, want tax cuts for the rich over health care for the poor, etc.").

Most importantly, she has NOT had any moderating effect on her father, but again she has the media at her feet....
