A left wing perspective of Mulcair and the NDP:
'A majority NDP government would be no better[than Harper. On top of its right-wing economic policies and support for Canadian imperialism, the party has demonstrated whenever it has held power that it is unwavering in its defence[sic] of the ruling elite and the bourgeois order. In a series of provincial governments since the beginning of the 1990s, including Bob Rae’s in Ontario, Roy Romanow’s in Saskatchewan and Gary Dewar’s[sic] in Manitoba, the NDP has confronted the working class head on by imposing devastating austerity measures to eliminate budget deficits and attack workers’ living standards.'
