There's no doubt that the trumped-up story about Nycole Turmel's one-time Bloc membership reflects the inevitable first real pile-on against the NDP in its new role as Official Opposition. But it's worth noting that the NDP also has an opportunity to turn that challenge in its favour - and the indications look to be positive so far.
For now, the main danger for the NDP isn't so much the certainty that the Cons and Libs will look to slam it at every turn as the danger of an intra-party split damaging its ability to fight back. And there's no doubt that concern trolls across the country will try to goad NDP members into contributing to just that type of internal breakdown.
But so far, there seems to be little indication that they're succeeding. And the more the NDP can keep a united front in the face of the other parties' contrived attacks, the more accustomed its new MPs will get to holding together - resulting in a stronger coalition once the siege ends. (Which may make the attacks all the more desperate as time goes by.)
What's more, there may even be an opportunity to shore up what might have been one of the greater risks for the party. While the NDP's Quebec sweep came largely at the expense of the Bloc, it's currently an open question as to whether the party can defend its seats against Lib and Con challengers without a seemingly strong Bloc in the picture. But the more energy the Cons and Libs dedicate to declaring that the bulk of Quebec's voters are unfit to participate in Canada's public debate by virtue of any past affinity for the province's once-dominant political party, the tougher they'll find it to win over those voters in the future - serving only to improve the NDP's chances of building on this year's electoral result.
That is, provided the NDP itself can hold firm and defend its newly-built coalition. But so far, all indications look to be positive on that front - meaning that there's ample reason for hope once the current storm passes.
