What is the point of opposing this coalition from the left? If the NDP were a serious leftist anti-capitalist party I can understand the sentiment of "no cooperation with the capitalists", but it isn't.
As reformist as the politics of the NDP may be, this "the NDP is just another capitalist party" line is just nonsense. Try visiting upper Westmount, Forest Hill or West Vancouver and let us know how many NDP supporters you find there.
The CAW's recent moves notwithstanding, most union leaders and activists have supported the NDP historically, even if the rank and file voted mostly Liberal and Tory. Corporate Canada doesn't support the NDP at all an in fact opposes it strongly, as it is a party clearly rooted in the working class movement, despite its pro-capitalist record in provincial office.
