The Liberal Party knew that financial expertise, or any other kind of expertise would get them back into power, but a good looking guy (or woman if one was available) with lots of image appeal, the right name (names are critical in federal elections), and a blameless past might. Such a leader could identify himself with "motherhood" causes like Indigenous neglect and abuse, feminism, the environment, refugees  and attract widespread support. Ignorance of major portfolios like finance, foreign affairs, trade and commerce, defence would be taken car of by experts like soldiers, business people, investors, lawyers. As long as no one did anything by halves that could have been done by quarters everything would be fine. Lately, the experts have been a little too exuberant and the Liberals along with their leader look vulnerable. Trudeau is no Chretien, or King or even Laurier but he might have to be to rescue the Party from its present crisis.
