Quebec Premier Jean Charest easily passed a confidence vote Saturday at his party's convention in Quebec City, nearly a year after winning a minority government.
Delegates gave him 97.2 per cent support.
Last March, the Liberals almost suffered defeat at the polls, winning just 48 of the province's 125 ridings.
Popularity polls then showed Charest trailing behind Action democratique du Quebec Leader Mario Dumont and Parti Quebecois Leader Pauline Marois in popularity.
John Parisella, a Charest advisor, said the Liberal leader has changed his tone since the last election by being more open to the other parties, and accepting his minority-government status.
"Mr. Charest's gains in the polls in recent months is because he has indicated to the population that he wants to make it work," Parisella told CTV Montreal.
"We're going to govern as if we are there for four years, but we're going to govern in a different style," he added.
In a speech to 2,500 party members Friday night, Charest said he had learned to listen more carefully to what voters want from their government.
"I listened and I've changed," he said.
Opinion polls now suggest the Liberals have a slight lead over the Parti Quebecois.
CTV Montreal's John Grant said Charest worked hard to boost his support among delegates before Tuesday's vote, spending more time with rank-and-file members and even double-checking his wife's ballot.
