They aren't afraid of Scheer and they aren't swarming the boards with talking points, you are deluding yourself. This just happened and it's Liberal supporter's (or those who can't stand the Reformer's) doing the talking ... without talking points. Harper was the only one who paid legions of posted to attack people on comment boards as he hired people to do so with federal money.

As for why they will get their talking points out at some point? Because they are an opposition party and they'd do the same thing even if the weakest candidate won.
