I kind of suspected this would happen. As the wave of attack ads and mud has tapered off, the Tories numbers have started to creep downwards; the Libs upwards.
Note that this poll is from the infamous Angus Reid, but the polling dates (March 6 and March 7) given do not seem to match up with the on-line poll they've been conducting recently, and which I wrote about here. Or at least if this is indeed that poll, Cherniak's responses to it (given yesterday) must have been excluded from the total.
Anyway, if it is an on-line poll, I still question the methodology, and would point to the weird Quebec numbers which seem to be at odds with every other polling source:
In Quebec, the Bloc has the support of 37 per cent of decided voters, with the Conservatives in second place with 25 per cent, and the Liberals third with 24 per cent.
Rationally or not, however, I am encouraged by the direction of the national trend (which is pretty close to Decima's).
