Alberta Premier Jason Kenney addressed United Conservative Party members at a special general meeting on Saturday and made his pitch to stay on as party leader. UCP members can begin voting via mail-in ballot on the future of Kenney’s leadership this week, with results expected May 18. But the lead-up to this vote has been rife with party infighting. Today, Maclean's Alberta correspondent Jason Markusoff explains what’s preceded this leadership review, the discontent within the UCP and why Kenney may have reason to be concerned regardless of the outcome next month.
