I thought I would do the numbers for the last week of polling, which is the normal EKOS survey, normal sample size. Not much different, but more "timely":
What is interesting about this poll, EKOS finds a noticeable uptick in those who think the Conservatives are headed in the "wrong direction". This change may reflect some negative opinion around the torture issue. With the issue dominating the news, Conservative believability clearly in question, there's a certain logic to it.
One other item, I noted that NDP supporters(and one "Liberal" I recall) were quick to rally behind the Ipsos Reid poll last week- despite the fact they previously criticized the consistent anti-NDP bias in their polling. It's a silly game, to cherry pick your polls, particularly from what you argued is a dubious source, just because it looks good. This poll reaffirms a wide gap between the Libs and NDP, a more sizeable margin. This isn't to say the Liberal number is particularly strong, but maybe talk of replacing the party as official opposition might just be a bit premature ;)
Looking ahead, with this torture story having more leg than Gwen Stefani, it's hard to see it working to the government's benefit. I'm not predicting a return to tied polling in the near term, but minor steady erosion is certainly a possibility. The looming embarrassment in Copenhagen, were criticism is a given, another rough patch on the horizon. We'll see if the gap holds...
