Chantal Hebert's excellent column on tonight's leaders debate

Excerpt:
"In the role of chief opposition prosecutor of the government, NDP Leader Thomas Mulcair has done an outstanding job in the House of Commons. At Thursday’s debate, he will have to morph into just as effective an advocate for his own cause.
"Two-thirds of voters are open to supporting a party other than Harper’s. Mulcair’s mission is to give those who have not in the past even considered voting for the NDP a licence to do so."
