Trudeau comes from an elite family but his behaviour intentionally eschews his elite status by wearing casual clothes, taking casual photos, and walking along side common citizens in Toronto's Pride parade. He humbles his elite status by playing a tv-perfect version of a common man.

Trump attempts to bolster his elite status but his behaviour unintentionally reveals an imperfect common man by arguing and bullying.
