Projection Update: Mainstreet 10/6-8

The following poll has been added to the model:
Mainstreet's 10/6-8 national poll (national results only; current weight among national polls: 35%)
For a full list of included polls, see previous Projection posts.

Note: The increased recency of this poll reduces the weight of yesterday's Forum poll from 26% to 22%.

Today's Mainstreet poll shows the Liberals and Tories both down, with the NDP being the main beneficiaries. There is again no corroboration of Forum's lead for the Tories, so the Conservatives are down slightly more than the Liberals in the projection.

Projection as of the latest national poll (midpoint: October 7.5)
CON - 144.4 (35.4%)
LIB - 142.7 (32.6%)
BQ - 24.9 (5.6%)
NDP - 22.1 (13.9%)
GRN - 2.9 (9.2%)

PPC - 0.5
IND - 0.5
