Canadian Prime Minister Justin Trudeau faced the threat of being knocked from power after one term as the nation held parliamentary elections on Monday.
The 47-year-old Trudeau channelled the star power of his father, the liberal icon and late Prime Minister Pierre Trudeau, when he won in 2015 but a combination of scandal and high expectations have damaged his prospects.
Polls indicate Trudeau's Liberal Party could lose to the rival Conservatives, or perhaps win but still fail to get a majority of seats in Parliament and have to rely on an opposition party to remain in power.
Not in 84 years has a first-term Canadian prime minister with a parliamentary majority lost a bid for re-election.
Trudeau reasserted liberalism in 2015 after almost 10 years of Conservative Party government in Canada, but he is one of the few remaining progressive leaders in the world.
He has been viewed as a beacon for liberals in the Trump era, even appearing on the cover of Rolling Stone magazine under the headline "Why Can't He Be Our President?"
Jason Kenney, Alberta's premier and a close friend of Scheer, calls the Conservative leader "an extremely normal Canadian" who is so nice he "can't fake being mean."
"Scheer has been hostage to the message," Nanos said. "His campaign has made him into an attack machine."
Scheer moved to calm the crowd and changed the chant to "Vote him out."
