Presuming there even is one this spring, the liberals can still post 3 more budgets before they actually have to go to the polls. The papers are all predicting an election, but they did that last year as well.
All depends on what the NDP chooses to do. The Golden Panel recommended a Corporate Tax as one of the revenue tools, and that's exactly what the NDP wanted. Hopefully that will be enough of a carrot for them to support the entire revenue tools package.
