As Albertans contemplate an October referendum that will see them choose between the province remaining in Canada or starting the process toward a future binding independence vote, the governing United Conservative Party is starting to show signs of internal strain and vulnerability of its leader, Premier Danielle Smith.

The political game in Alberta has changed. The debate around the future of the province has ignited emotion on all sides, and has morphed into "primordial politics," a deeply-entrenched, identity-based attachment to your side.

This week on West of Centre, host Kathleen Petty is joined by two long-time observers of politics in Alberta, with deep knowledge of how the political landscape has evolved. Anthony Sayers is a political science professor and director of Canadian governance policy in the University of Calgary's School of Public Policy; and David Stewart is a professor emeritus in the University of Calgary's political science department. Both are frequent collaborators who have co-authored a number of papers and academic book chapters, and they have a new book that will be published this summer, The Dawn of Competitive Party Politics in Alberta: An End to Solitude.

In this rare conversation, Sayers and Stewart tap into the past, where the governing Progressive Conservatives enjoyed little opposition until the Wild Rose Party came along and posed a credible threat. But the merging of the parties has pushed the UCP further to the right, forcing the party to keep its base motivated and ready to turn out in an election. They say the UCP is a different party from when Jason Kenney was leader, and even more difficult for Smith to manage.
