The correct interpretation is, in the 2015 Canadian election, 68.1 % of Canadians voted for left of center candidates, with Trudeau winning a plurality of 39.5%.
In the US election Clinton won the popular vote 48.1% to 46.2% with Trump winning the election because of the vagaries of the electoral college.
Four years earlier Trump tweeted outrage because the numbers on his TV screen, showed that Romney was nearly a million votes ahead of Obama in the popular vote count, but Obama was projected to win the electoral count.
Eventually, Obama pulled ahead in the popular vote, and he would go on to win a majority.
Trump’s tweet from four years ago reveals that he thinks one word describes a presidential candidate who gets fewer votes than his rival: loser.
