You are wrong. The budget was not the issue. It was the Economic Update that supposedly pissed off the Opposition. The Opp are claiming that the Conservatives are not doing enough to try and stimulate the economy.

A few things can happen here now and all roads lead to the Gov General. The PM is going to try and get her to end the current parliamentary session until January which would allow the Tories to retain control for a while longer. The Opp on the other hand are going to try and get her to recognize and allow their alliance which would give them control and make the Liberal leader the new PM. The GG also has the option to ignore them both and allow parliament to continue. If that happens the Opp will take the first non-confidence vote opportunity and bring down the gov't forcing yet another election.
