Why Canadian politicians love Tim Hortons

Tim Hortons and Burger King agreed to a merger this week, prompting Burger King to assure Americans it would continue paying US taxes, and Tim's to promise Canadians that nothing would change on this side of the border. The merger is more than a business story in Canada. To some, Tim Hortons has become as synonymous with Canadian culture as hockey, maple syrup, and politeness. The "Tim Hortons voter" is a familiar trope for politicians and pundits of all stripes. Douglas Hunter, author of "Double Double: How Tim Hortons Became a Canadian Way of Life One Cup At A Time", joins Brent to discuss the origins of the donut chain's identification with Canadian nationalism - and why it appeals to Canadian politicians.
