What went wrong with the Liberals’ verification system and what does it mean for the future?

During a campaign stop in Calgary two weeks ago, Mark Carney acknowledged there had been a cost to his party’s efforts to guard against foreign interference during the race that made him the new Liberal Leader.A reporter had asked him what he would do to stave off foreign meddling in nomination and leadership contests. He cited the “rigorous process” the party had used this spring in choosing a leader. “Fewer people would have voted than otherwise would have happened, but that was a price in that case worth paying,” he said.
