Did Quebec reject the Bloc to make a coalition easier?

There has been lots written the last couple of days about the collapse of the Bloc and the NDP surge in Quebec and so far I have not read anything that really explains what happened. Did BQ supporters all wake up one day and decide to toss out a party that for years has enjoyed their support because of something Duceppe did or did not do? Were they all taken in by the guy from downtown Toronto with the big smile and equally big spending promises? 

While I don't claim to know the answer I do have some thoughts and a possible piece of the puzzle as to why Bloc supporters decided to abandon their party and support the NDP.

The coalition.

Whenever the idea of a coalition has been discussed it has been quite clear that having Bloc MPs as part of any coalition was not to the liking of most Canadians. During the original coalition crisis both the Liberals and NDP were desperately trying to spin that the Bloc were not actually part of the coalition, only that they would be supporting it, and Ignatieff himself had this to say as to why he didn't enter into the deal he had signed: "I could be sitting here as your prime minister, but I turned it down because I didn’t think it was right for someone who believes in the national unity of my country to make a deal with people who want to split the country up," 

Having separatist Bloc MP's either in or supporting a coalition government did not fly in 2008 and was never going to go over well with Canadians. Bloc supporters were as aware of this problem as much as anyone else but what to do about it.

The solution: Drop the Bloc and elect enough NDP MPs so that a coalition would not only be legitimate but it would have a much better chance of being accepted by the rest of Canada.

It makes sense and possibly explains why dedicated separatists tossed their own party and blindly voted for NDP candidates some of which were barely old enough to vote themselves, did not speak French, or have NEVER even been to the riding in which they were running in.

Your thoughts?
