the way to understand this is to realize that the liberal party has essentially reorganized itself as a free market corporation, rather than a political party. if you talk to people in the liberal party, they apparently reject the westminster-democracy rule that sitting mps can vote for their own leader. this is wrong and delusional, and i'd like to see a caucus revolt in the canadian liberal party that does result in a change of leader just to re-establish the actual rules, rather than these make believe rules the liberal party invented in a back room somewhere, but it demonstrates what carney is: he's the ceo of the liberal party first, and prime minister second. the way he became prime minister demonstrates that.

keeping that in mind, noam chomsky explains mark carney in the following clip:
