I suspect the majority of public and private sector union members in Canada voted NDP, but it most certainly dropped from 2011.NDP needs to go back to the left. They lost a lot of support from the labour groups that always supported the NDP. A lot of union workers voted liberal in the last election.
And Mulcair couldn't connect with young voters like the way Layton and Trudeau did
That's my experience as well. None of the NDPers I know voted Liberal last time around. If anything, many of my NDP friends seemed to be in a state of panic the week before the election and were all signing up for get-out-the-vote efforts. The entreaties on Facebook in support of people like Jennifer Hollett, Paul Dewar, Peggy Nash, etc. reached a fever pitch.[...] Every NDPer I know is unabashedly left wing - most support the Leap Manifesto, BDS Movement, Black Lives Matter and bold anti-poverty measures. As dispirited as they are, none of the them have automatically become Liberal supporters, especially given Trudeau's strong cabinet connections to Bay Street, his push for the TPP, and the Saudi Arms deal.
