I figure some of the "stable government to look after the economy" vote they got this past time is potentially up for grabs. If the Liberals would re-orient themselves in the direction Stockholm suggests, they could take back some of their seats on the margin like the Willowdales, North Vancouvers,
...except, Vancouver North is turning out high profile NDP endorsers for Thomas Mulcair (i.e. Mayor Mussato, Councillor Keating).
This is part of the reason Mulcair is such a threat. He is able to appeal to well-heeled, well-educated, drifting Liberal crowd. In the GVRD at least, I think Mulcair's political experience (as a Liberal) and environmental plank is key to this appeal. (I think and I think Mussato and Keating also think) Mulcair is able to attract BC Liberals with composters.
If that is the case, the Liberals will cease to exist in Western Canada.
