The poll by Abacus Data exclusively for Sun News Network finds Charest has an approval rating among Liberals of 47% and a disapproval rating among Grits of 15%.
Two other potential Liberal leadership candidates from Quebec do much better.
MP Justin Trudeau has an approval rating of 70% among Liberals while MP Marc Garneau's approval rating is 51%.
Interestingly, among those who voted Conservative in the last election, more give Trudeau the thumbs up (23%) than either Charest (19%) or Garneau (17%).
Abacus did not ask respondents about any other likely Liberal leadership candidate such as Nova Scotia MP Geoff Regan who, when asked Friday about his intentions to run, simply said, "stay tuned."
Among all voters in Quebec, Trudeau has higher favourability (40%) than Charest (28%) or Garneau (23%).
Abacus polled 1,208 Canadians between Sept. 14-18 using an online survey. The poll participants were chosen at random from an online database of 150,000 volunteers. The pollster weighted the survey sample by age, gender, region and education level according to the most recent census data. The pollster's method is widely used and, according to the industry association of which the pollster is a member, is believed to be capable of producing accurate results.
