His replacement by Turner in 1984 was largely a product of Turner's showing at the 1968 convention. After Winters' death, Turner's third-place showing made him the leading runner-up. Turner's political and organizational skills were much lauded in 1968, establishing him as one of the highest-profile Liberals. Turner was succeeded by Jean Chrétien in 1990. Chrétien had originally backed the leadership bid of his mentor, Mitchell Sharp, but joined Trudeau's campaign when Sharp withdrew in favour of Trudeau. At the convention, Chrétien became one of the Trudeau team's leading figures, playing a crucial role in recruiting a number of other cabinet ministers to the Trudeau fold. Chrétien continued to be Trudeau's loyal deputy until Trudeau's retirement in 1984. Chrétien won the Liberal leadership in 1990, in part by claiming to be the heir to Trudeau's vision and policies. Paul Martin, who would himself become Prime Minister (2003–2006) was also at the convention, not as a Liberal operative, but as a close advisor to his father Paul Martin Sr. His father's poor showing, permanently ending his long dream of becoming Prime Minister, has long been cited by biographers as the source of the ceaseless ambition by Martin Jr. to win Canada's top job.
