Mr Trudeau exudes energy and fun, when he speaks it's clear he's addressing women and the young, he legalizes pot, he spends his time in campaign mode, so it's clear he's in sync with today's Canadians.  He's a party-nation's Partier-in-Chief.  Conservatives and NDP are still about substance, about "traditional" politics, while Liberals have caught the winds of change vibe that prevails today.  The Conservatives don't get there's a new world coming, or so Canadians have been educated to believe, so Mr Scheer and his party don't really have a hope, no matter what they do.
