I dunno. I think the CPC's "run attack ads and nothing else" campaign is half the reason that Trudeau won a liberal majority up here.
Obama's "hope" campaign was pretty damn effective too.
i mean
that's pretty typical PC. part of the reason they're so ass.
that said, liberals tend to like an attack ad here and there themselves. they were good at laying off for trudeau's campaign and letting harper shoot himself in the foot.
