Honestly, we'd be in a better spot if Tom Mulcair was still in charge. Or, if Charlie Angus had won instead.
Singh is okay, if you're campaigning in the heady days of 2015-2019. He's not the person you want now; you want an empathic economic populist--the Canadian equivalent to Sanders, if you will.
Singh isn't that. Layton wasn't, either. Layton did well because the Bloc and Liberals both collapsed and Harper had a natural vote ceiling.
