Paul Martin succeeded Chrétien as party leader and prime minister in 2003. Despite the personal rivalry between the two, Martin was the architect of the Liberals' economic policies as Minister of Finance during the 1990s. Chrétien left office with a high approval rating and Martin was expected to make inroads into Quebec and Western Canada, two regions of Canada where the Liberals had not attracted much support since the 1980s and 1990s, respectively. While his cabinet choices provoked some controversy over excluding many Chrétien supporters, it at first did little to hurt his popularity.
