Majority of Canadians still see through Harper. Budget fails to impress.

globeandmail.com: Budget fails to quell criticisms of Prime Minister, poll suggests

Although this poll shows that a majority of Canadians support the budget, Harper and his Conservatives are on shakier ground.
Some points to note: 

... voters are now less likely to support the government because of the budget.
... 69 per cent say they still blame Mr. Harper for causing an unnecessary
political crisis late last year when he should have been focusing on
the economy.
...When asked to name the top three beneficiaries of the budget, large
corporations showed up most often. Poor Canadians and older/retired
Canadians were seen as those benefiting the least.
