If Liberals, lead by the most incompetant nobody in recent years - yes, including Dion - had the interest of the country at heart, they would insist that Harper fulfill his promise of having Federal Elections at set times, rather than parrotting something that they NEVER HAVE, ANYWAYS: confidence in Conservatives.
They would let this government go and dig their own grave, until it would be time for next election.
But, appearently, smallmindedness and pettiness are the strongest suit and the hope of the Liberals.
