Projection Update: Mainstreet 7/30-31

Update Aug. 9: Due to small modifications to the model, parts of this post have been revised; the revisions are underlined.

The following poll has been added to the model:
Mainstreet's 7/30-31 national poll (current weight among national polls: 38%)
The high weight is due to this poll's relatively large sample size and the dearth of other recent polls. Because Mainstreet's earlier poll now has a weight of -12%, it does not disproportionately dominate the polling average. View the poll weighting methodology here.
For a full list of included polls, see previous Projection posts.

Seats projected ahead as of the latest national poll (midpoint: July 30.5)

LIB - 155 152 (32.8%)

NDP - 17 18 (13.0%)
