Well if John Q Conservative hater did it I would agree. But for a Liberal staffer to do it isn't really called for.
I remember the Liberals got all excited in their pants over a flash ad that had a Puffin pooping on Stephan Dion. Now that's a prank, this is far more mean-spirited.
As for the RoboCalls thing, I don't think anyone has defended the Pierre Poutine guy even the most ardent Conservative supporter says Election fraud is wrong.
But, without any evidence, people are theorizing that this incident is far more reaching. I would strongly push back against that without more details.
Even the Star doesn't provide specific, they just guess that this can't be isolated to Guelph.
Well if you don't have evidence to the contrary then STFU.
