Stéphane Dion - Strong priorities, strong leadership

So if Stéphane Dion is not a leader, why do the Conservatives need to spend millions on more attack ads? Why didn't the first ads do it? Looks to me like Dion is incredibly strong to be able to withstand five waves of attack ads. Looks to me like Harper and the Conservatives are really scared of him. And they should be. Strength, courage, honesty, integrity - pretty scary stuff if you're a lying bully.
