I still think the biggest reason for his success as a propagandist, at least in terms of nothing sticking to him, is that there's really so little relevance to what he does anyway.
The thing that really pisses me off is the census. By killing its effectiveness he's taking away the effectiveness of the bureaucratic machinery that is far more important to our everyday lives. It means that money will be spent without having a clear idea of the needs or aims beforehand, and money will not be spent in some areas where it could be desperately needed - leading to much greater costs down the line. All the government in Ottawa has to do is allow for good information to flow and direct an appropriate response. They've given up just about any other powers that mean anything. Now the ability to obtain good information has taken a huge hit. That leaves fighter jets and disinformation. And that game can and will be played by both major parties. Fuck them.
