He doesn't scare the Cons at all. Not in the least bit.And that proves what? It could just as easily have had an positive influence on his DNA. I think, by the crap being thrown in his direction, that the cons are terrified that he will run. I have no interest in the Liberals but if Trudeau scares Cons, I would vote for him just to piss them off.
P.S. Weed can't alter DNA.
