Justin Trudeau elected new Liberal leader in landslide with 80% of voteJustin Trudeau has been elected to lead the federal Liberal party in a resounding first-ballot win.Trudeau, eldest son of former prime minister Pierre Trudeau and the Liberals' undisputed star, swept 80% of the vote in a final field of six candidates.The outcome was widely seen as a foregone conclusion since Trudeau launched his campaign last October. Now, the Liberals are hoping that the party's undisputed rock star will be able to re-establish their reputation as the country's natural governing party.His ascension to the Liberal helm will, at least in the short term, put paid to the notion that the next election will be a polarized two-way fight between the Conservatives and New Democrats, with the Grits destined for oblivion.Just the prospect of the 41-year-old Montreal MP's victory was able to boost the Liberals, reduced to a third-place rump in 2011, back into contention in public opinion polls. They are now running even with or ahead of the ruling Conservatives. The NDP has been relegated to its traditional third place slot after vaulting into official Opposition status in 2011 for the first time in its history. (Michelle Siu for Postmedia News)
