Considering the Liberal record of hand-sitting through 43 votes in the last couple of years, it will be a big step for them to be responsible again.
"Mr. Dion said his MPs are upbeat about the role they will play in the
next sitting of Parliament, and have learned some important lessons
from the last two years in opposition."
This remains to be seen if they have "learned some important lessons from the last two years in opposition".
From what I have read, Harper intends on running the same kind of show - making everything a confidence motion - again. So, if the Liberals are responsible and vote against legislation that would be bad for Canada, we will have another election very soon. (Harper, of course, will try to lay the blame on the opposition, but, I think Canadians will see through his little game of trying to force elections instead of trying to make things work.) Then, maybe people will see how irresponsible the Harper government is and kick them out.
Here's to hoping that the Liberals get it together, but I'm not holding my breath.
