You could say that Trudeau is just continuing on with the theme of living in a post-truth world, by making up his own reality for his followers to dwell in.

It appears to be the new way to interpret the world.

Trudeau showed the way for Trump, but mastering new media, and thus overstepping the older 'trusted" sources to speak directly to and engaging with one's followers..Think about is, a selfie with Trudeau probably gets posted on Facebook, passed around friends etc. It easily has a "warmth halo" of 10 -15 other people, who were not there, and likely not immediately predisposed to Trudeau, one way or another. 

The fact that one starts to believe one's own BS after a while is a concept "as old as the hills"..and thus Trudeau himself, doesn't believe he is not, or cannot do anything wrong.
