OR, at least they will if they get the chance.
The NDP, Liberals and Bloc have all indicated they won't support the economic update from the government, which is a confidence motion. Nobody reading this blog needs to be told, if a confidence motion fails, the government is close behind, and it's election-time again.
A grand Harper plot to give Kirk Schmidt another shot at Calgary West? Unlikely... but, I suppose it's possible...
The NDP and Bloc, both feeling they have momentum and room to grow at the cost of the Liberals, will vote against the economic update.
That puts the ball squarely in the court of the Liberals - hemorrhaging money, in the middle of a leadership race. In a weaker position than at any time in the history of their party. But, they DO have options... and I say "they", because anyone who thinks Stephane Dion will make this decision by himself and have the caucus follow his lead is completely out to lunch.
Option 1: Don't show up. This is a tactic they mastered in the last parliament, and it can work here as well. If a dozen or so Liberals come down with the flu the day of the vote, then the party caucus can vote against the update without bringing down the government.
Option 2: Turn over the Prime Minister's chair to Jack Layton. If they decide to bring down the government over the issue, the Liberals can propose a coalition government for the consideration of the Governor General. Since their own leader is on the way out, the Libs would have to support Jack Layton for the leadership of the coalition - because, if they didn't, then the numbers game would result in the coalition selecting the leader of the 2nd biggest party within it as Prime Minister Gilles Duceppe.
Option 3: Amend, amend, amend. The Liberals have a strong enough caucus, and enough in common with the NDP, to make enough amendments to the update to make the Tories want to kill it themselves.
Overall, I suspect the Liberals will try to go for Option 3, and eventually settle for Option 1. But they have the most to lose, and so the onus is on them to figure out what to do to keep their pride without paving the way for their party's electoral annihilation.
