Crossposted with Stockholm-- to answer Stockholm-- I disagree completely. Trudeau is not dumb at all. He is immature. The first is not curable -- the second with intense will and effort is.
I do not support Trudeau or particularly welcome his candidacy but I also do not underestimate the machine, the name, the people behind him and the potential for damage he can do. For NDP partisans you should not either. If the NDP takes Trudeau for granted we will be in for a surprise-- he will be a formidable opponent very different than Dion or Ignatieff and the NDP will have to have a strategy to oppose him. I'd start with the idea that he is a privileged actor who can play the part without being truly in touch. Thinking Trudeau will implode on his own without help is a very, very bad plan. His weaknesses could be largely concealed until after he becomes PM.
