Might also be interesting to see whether the Green Party is still alive and whether it can get a few percentage points.
I'll be surprised if their vote percent isn't up from 2011. They have a strong candidate, we no longer have Jack, there will be no argument for tactical voting, and by-elections usually have a lower turnout. What will be interesting is, will their raw vote total even go up? It might. Which, a week before the leadership vote, would be a reminder to everyone that non-partisan and green voters may be skeptical that the NDP will actually do anything about proportional representation, and if our new leader is less vehement about it than Jack was, they may not vote NDP next time. The Green vote across Canada fell from 937,613 in 2008 to 572,095 in 2011, most of which switched to the NDP, partly to stop Harper, partly because of NDP policy on PR.
