So Trudeau called a snap election for Sept. 20, hoping to earn his Liberal Party a ruling majority. Instead, his numbers dropped instantly, confounding many. With 12 days to go, he's likely to end with a weakened minority government or even a humiliating defeat. "The Liberals likely called the election thinking that they would be able to run on their pandemic record, bask in a vaccination halo and get ahead of the post-stimulus economic adjustment," said Nik Nanos, an Ottawa-based pollster at Nanos Research Group. "That's out the door now."

OTTAWA - Last month, Prime Minister Justin Trudeau was convinced of two things: his successful vaccination strategy had made Canadian voters grateful, and his main opponent, Conservative Leader Erin O'Toole, was somewhere between unpopular and unknown, reported Bloomberg News.

So Trudeau called a snap election for Sept. 20, hoping to earn his Liberal Party a ruling majority. Instead, his numbers dropped instantly, confounding many. With 12 days to go, he's likely to end with a weakened minority government or even a humiliating defeat.

"The Liberals likely called the election thinking that they would be able to run on their pandemic record, bask in a vaccination halo and get ahead of the post-stimulus economic adjustment," said Nik Nanos, an Ottawa-based pollster at Nanos Research Group. "That's out the door now."

Many start with the mood of the electorate. They say voters feel taken advantage of by a politician seen to have turned a health crisis into a power grab. In one poll, nearly 60%said the country shouldn't be having an election. Canadians are comfortable with a minority government and have no special desire to help the Liberals gain full parliamentary control.

Others point to tactical factors: On day one, Trudeau struggled to convey a clear message about his vision and the reason for the vote. On day two, O'Toole's Conservatives released a platform focused on the economy and free of much of the party's traditional ideological baggage.

After Trudeau's lead evaporated, the Liberals started focusing on wedge issues -- abortion, private health care, anti-vaxxers and gun control -- aimed at painting the Conservatives as regressive. The Tory leader hasn't taken the bait.

Frustrated Liberals talk about an exhausted group of insiders burned out by the pandemic. They say the government has failed to replenish itself with new talent and yet came to the election with excessive self-confidence that led them to believe in the inevitability of victory.

"I don't understand how they could have been so tone-deaf about the mood of the Canadian public, about peoples' total preoccupation with Covid and some kind of return to normal," said Peter Donolo, a vice chairman at Hill+Knowlton Canada who was communications chief to former Liberal Prime Minister Jean Chretien.
