Prime Minister Stephen Harper suggested the opposition would have tax-cut hungry voters to answer to if it attempts to stall or mess with his new Conservative budget.
Harper issued the challenge during a raucous question period in the House of Commons Wednesday, when Liberal and New Democrat MPs slammed the fiscal plan a day after its unveiling.
Opposition Leader Bill Graham called the government's first budget "neo-conservative" and said it neglects the environment and abandons children and aboriginals.
Graham said the fiscal plan puts wealthy Canadians ahead of the poor -- that Tory tax measures raise income taxes for those who earn the least, and benefit those who earn the most.
Harper fired back, saying "it's a sad spectacle to see a party which so disappointed Canadians for 13 years now criticizing the best-news budget this country has ever seen."
He said if the Liberals are so opposed to the budget: "They can grandstand here but we'll see what position they take over in the Senate where they have a majority."
The Liberal-dominated Senate can delay the budget legislation (Liberal senators have done it before, delaying Brian Mulroney's Conservative budget in 1990 that brought in the GST), but doesn't have the power to bring down the elected government. (source)
