Here is the most recent Harris-Decima poll. It shows the Liberals pulling back a bit from their tie with the Conservatives two weeks ago due to weaker results in BC and Québec. Accordingly, adding this poll to the aggregate projection gives:
CON - 124
LIB - 100
BQ - 48
NDP - 36
The Tory lead in national voting intentions averaged over the last few polls is now 1.5%.
