read some of the answers over there from supposèdly individual posters. I think they're paid bashers but have no proof of it.
It's possible to match writing style to blocks of text and determine if specific posts are written by the same person. It would be interesting to see how many posters are also at work on other sites and under different identities.
But it doesn't really matter. Voters form opinions on what they see, what they hate and what they are most tired of. If Harper really was a wise and long term thinker he would have bowed out a year ago and let somebody like Kenny get a chance. But he is like most politicians and pushes too far and hard. He will go when he is thrown under the bus by voters or his own party.
I find it interesting the effort by vastly different groups looking to oust the Conservatives. You have groups like anonymous, duffy, and a multitude of others ready and willing to take a shat on Harper. As much as the Conservatives can brag of a big war chest they are one revelation away from losing the prize.
