I think the most straightforward lesson to take away from the tarring of Linda Keen as a Liberal hack and her subsequent firing is that we have yet another example of how the Conservatives view everything as a partisan opportunity. This is the Karl Rove strategy perfected in the US.
What I’m going to suggest to the Liberals and the NDP and the Greens is that, by Harper’s rules, everything is fair game. Every time you can score partisan points, recognize that, if Harper was in your position, he would not hesitate. I don’t know that this is the most tasteful way that politics is done, but you’ve got give as good as you get, right?
