Prime Minister Mark Carney is marking his first year in office with strong approval ratings that mirror the early popularity once enjoyed by former prime minister Justin Trudeau, highlighting a typical political “honeymoon” period, writes Lori Turnbull. Historical trends suggest such support often declines at the 15-month mark. “There is some evidence to suggest that Prime Minister Carney’s political “rock star” status might have longer legs than the initial generous spirit/benefit of the doubt extended to all new prime ministers,” Turnbull says, noting he’s not a “typical politician” and he seems to be transcending regional and partisan lines. Ongoing challenges such as the affordability crisis and concentrated decision-making could erode public support over time, however.
