Cooperation is two way Master. Harper has promised to bring in exactly the same budget that was defeated to cause th4e election. If he has the same or fewer seats in the new house, that would seem to be rather confrontational and counter productive. So if he proceeds and is defeated who isn't "cooperating?"
NDP Forming GovernmentEven a minority government, following an election, has a window of opportunity to force legislation through the House. This, of course, is not enshrined in the constitution, but it stems from the very nature of the circumstance. The election produced a winner who has the duty of governing.
Procedurally, the current election was not triggered over the budged but because the government was found in contempt of parliament. It isn’t really a surprise if the Conservatives bring in the same budget before the House. For the most part they have campaigned on the budget and the other partiers are aware of this. So if the Conservatives were to be re-elected and attempt to implement the budget that the people voted for – vicariously, of course – then to defeat the government on the budget would seem as though the opposition is obstructing the economic recovery of the country, a position that no political party wants to find themselves in.
Assuming that the NPD form the official opposition and the Conservatives have a strengthened minority, I think it would be difficult for them to resist a budget shortly after the election. It would seem like a power grab if the NDP tried for form government without being elected to the office, and their gains would possibly dissipate if Parliament were again dissolved.
What I’m saying is that if the Conservatives win the election and the other parties form an arrangement (as would be necessary) to topple the government within the first 100 days, the optics of this
coup (constitutional though it may be) are hardly favourable.
An NDP government, supported by the Liberals and the Bloc, would be, in my opinion, worse for the NDP than being leaders of the official opposition. The Liberals as a junior partner in a coalition (if indeed they agree to this in the first place) would be seeking an opportunity to topple the NDP government in order to reassert their once unshakable hold on the Prime Minister’s Office. An NDP led coalition would not only look bad in the way it was achieved but also would have some internal concerns.
All this would simply add lustre to the Conservative offer of stability. Bearing that in mind, it would be better for the NDP to serve four years or so as leaders of the opposition (If they were elected as such) and then challenge the government rather than aiming to move from fourth to first place in one shot.
