EKOS is startlingly divergent from the others. Like, to the degree where if you miss by that much as a polling company, you pretty much destroy yourself. I wonder what's leading to such very different results?
Parsing things a bit farther though, it looks liek each of the polling companies show a narrowing in their own poll to poll data:
Leger | CPC +26 on Jan 12 | CPC +18 on Jan 25 | Down by 8% | 5 days old |
Ekos | CPC +9 on Jan 18 | CPC +3 on Jan 25 | Down by 6% | 5 days old |
Nanos | CPC +24 on Jan 17 | CPC +17 on Jan 24 | Down by 7% | 6 days old |
Abacus | CPC +26 on Jan 12 | CPC +21 on Jan 24 | Down by 5% | 6 days old |
Mainstreet: | CPC +29 on Dec 16 | CPC +19 on Jan 13 | Down by 10% | 17 days old |
The polling itself I put little stock in, but consistently all of the big polls that have reported since Trudeau's resignation announcement show some reversion away from the extreme highs the CPC were enjoying immediately prior. EKOS is still way out there alone though.
