Generally, the first batch of post-election polls show a government maintaining, or just as likely, increasing their support, as the electorate resign themselves to a new mandate, they tend to rally behind the victor. The fact we see the opposite here, suggests the Harper government doesn't enjoy the confidence it claims, voters are volatile, any support tepid at best. Conservatives down in Quebec, Ontario and a seismic shift in the "west":
Committed Voters - Western Canada (N=299, MoE ± 5.7%, 19 times out of 20)
Conservative Party 38% (-14)
Liberal Party 27% (+11)
NDP 23% (+1)
Green Party 13% (+5)
The above might be a reflection of a rapidly deteriorating economy, coupled with a Dion-less Liberal Party, making a voter "shift" (yes shift) easier. Whatever the reason, it is interesting that the considerable Conservative loss moves directly to the Liberals, suggesting there may be some latent hope for the party after all.
This poll means little in the grand scheme. The numbers don't really matter, because an election isn't in the cards, but it does reaffirm the view that many Conservative voters aren't fully invested, they will revert back to an alternative, if given the proper nudge. The numbers might also reflect some fallout from saying one thing during the final days of the campaign, then completely and UTTERLY contradicting one's self in mere days, once a mandate was secured.
