We have a winner

During Canada's 2008 federal election campaign Stephen Harper, the Conservative prime minister, warned that an opposition promise to introduce a carbon tax would "screw everybody". Partly for that reason, Mr Harper is still the prime minister. But in the same year, the provincial government in British Columbia introduced a carbon tax of its own. Despite the levy, its economy is doing well. What is more, the tax is popular: it is backed by 54%, says a survey in the province by Envi-ronics, a pollster. Gordon Campbell, the Liberal premier who introduced the tax, won a provincial election the next year.
