What is "trudeaumania"

Trudeaumania was the nickname given in early 1968 to the excitement generated by Pierre Trudeau's entry into the leadership race of the Liberal Party of Canada. Trudeaumania continued during the subsequent federal election campaign and during Trudeau's early years as Prime Minister of Canada. Decades later, Trudeau's son, Justin Trudeau, drew a similar international reaction when he became Prime Minister himself in 2015.
