Political knitipicking distracts from important issues

I normally admire Bob Rae, but in recent times he is revealing himself as a down and dirty political animal determined to win at any cost. His abandonment of the NDP to join the Liberal party was one such decision. He wants to be on the winning team - nothing wrong with that I guess. But his news conference today regarding Harper's 2003 statement in parliament about Canada's participation in Iraq war in 2003 being lifted from the Australian PM's speech two days previous is sickening.
I am the last to guy to let Harper off the hook, but in this case, clearly a staff speechwriter cut corners, lifted the material and passed it on to the boss. Bob Rae carrying on as if Harper has been exposed as a criminal is the kind of tawdry, nasty, and meanspirited behavior that turns people off the Liberal message, and off politics in general. Dion has jumped on the wagon and is calling for Harper to be "thrown out" (by whom and to where is unclear). Canadians are mostly decent people and while I personally don't much care for the Tory message, I don't like the idea of using cheap shots to defeat them. If that is what politics is about in our country today, we might as well become another U.S. state.
