Jagmeet simply did not have the support to remotely have a chance to win instead of PP or Carney. That's the context in which Carney "was the best choice at the time." Not much else. I agree we'd been better off with Jagmeet.
I think things would shake out differently in a couple of years with Avi's NDP on the docket. Perhaps not an NDP gov't but I think we'd get significantly more seats than the last election.
