The problem is the cult of perosnality.
Trudeaumania v1.0 and v2.0 were all based on a "new" face coming in to seismicly shift the status quo. Canadians wanted new ideas, new ways to do things, and wanted to get ahead from where they saw themselves; both geopolitically and domestically.
What amounted in both cases were 2 very flawed individuals that broke their promises routinely, acted with contempt towards our institutions and populace, and did little to move the ball down the field (or in some cases brought us back a few yards).
The infatuation is not with the results, but with the ideals. Change, renaissance, rejuvenation, forward thinking. The fact that its tied to an individual just goes to show the power of branding and image.
Give it time and we will see the same said of PP and the CPC, should they not deliver on their promises. Mulroney faced the same widespread support post Trudeau because it was promising change, and then reality set it.
