After a slip after the 2007 budget, which raised taxes, the Liberals have returned to the astronomical polling numbers they enjoyed shortly after taking office. The Liberals currently stand at 60% in the quarterly CRA poll, compared to 30% for the Tories.
The Telegraph-Journal has extensive reporting on the poll, which has not yet been posted on CRA's website.
The trend looks pretty good for the Grits... Maybe the Tories should think about picking a leader sometime soon?
UPDATE: The Gleaner article has more detail.
