This support could be a breakthrough for the NDP, not only in the province of Quebec, but they are also hoping that this could signal a flood of support for the party throughout the country. Jack Layton, NDP leader was born in Montreal and recently took in a Canadiens game. That, paired with the English and French leaders debate was what many think propelled him to the top of the polls in the province.
This is a big signal to the NDP that they are doing something wrong in the election. They need to do something drastic to raise their standing in the polls, because unlike the other parties, Quebec is the only province that the Bloc runs in. If they lose the public opinion, it drastically reduces their chances of having as many members in Parliament as the last election.
