What does "running up the margins" even mean for the NDP? I doubt they will be getting over 70% in many seats (if at all.. maybe Nickel Belt?), and very few over 60% margins. Again, in 'NDP strongholds' most who would potentially vote NDP already did so last time. NDP gains will be made mostly in non-NDP seats.
I agree; I could see the NDP at +60 in say Toronto-Danforth, maybe Parkdale-High Park, Hamilton Centre, Essex and both Windsor seats, the North, basically the seats they currently hold. But I can see the NDP winning +50 in those pickups like Davenport, Toronto Centre... maybe even University-Rosedale and Spadina-Fort York.
