Would it be best to differentiate the party from the Liberals on an issue like the carbon tax plan or would it be best if the party supports the government?

Your job: What stance will most benefit an opposition party?
Pick a major, national opposition political party . Imagine that you have been hired as a political consultant as the party seeks to increase its share of the electorate before the next election.
Please advise the party’s political director, Max D. Vote, on how to best respond to any news of the Oshawa’s plant closing . Max D. Vote wants to know whether this closing should be an opportunity to criticize the government’s carbon tax plan, framing it as unfriendly to business, or whether the party should embrace at least some aspects of the carbon tax plan in an effort to grow sectors of the economy other than manufacturing and the Alberta oil sands.
