Prime Minister Stephen Harper stirred up the strange world of #cdnpoli when people noticed he kept calling Liberal Leader Justin Trudeau by his first name only.
Soon other Conservatives were doing it too. Was this their subtle way of throwing shade at Trudeau? Were they trying to make him look like a child?
Critics pounced on this subtle dig. They said it was unbecoming of a prime minister.
To which Harper's campaign manager had a pretty devastating comeback about who started the first-name-only thing.
Harper was actually asked about this in one of his coveted media availabilities.
But if you think Harper is being passive-aggressive, he's got nothing on Tom Mulcair. The NDP leader won't even acknowledge that Justin Trudeau has a first or last name.
Three days down, only 75 to go until the election.
