In leadership news...
So this sets us up for a Mulcair-Topp battle for Stornoway. All early indications are that Topp and Mulcair will play nice with each other, while their supporters mercilessly smear each other in the press.
After watching Liberals do this very thing for years, I'd caution against this war-by-proxy. You'd be amazed how many people pick a candidate to support just because someone else's supporters come across as complete assholes. By sending their supporters out to do the dirty work, Mulcair and Topp are opening the door for someone like with Paul Dewar or Nathan Cullen to come "up the middle" and win.
I know it sounds unlikely now given all the media attention on Topp and Mulcair, but this is a long race, and things like this have been known to happen before.
