Justin Trudeau's latest ad, in which the 41-year-old leader of one of the western world's leading political parties appears wearing the sort of outfit a fratboy might toss on to take out the trash, was offensive not for any sartorial prissiness, but because it reflected an unsettling lack of dignity for a supposed prime minister-in-waiting. For a man who's already benefited enormously from exploiting sex appeal for electoral benefit, now that he's a parliamentary leader, the least the guy could do is at least pretend he's got more to offer voters than the suggestive outline of his pecs. But then again, the Tories already declared J-Tru's body fair game in ads of their own, didn't they?
