The Tory dominance was finally broken in the 2015 general election, when the Alberta New Democratic Party won power under Edmontonian Rachel Notley. Notably, the NDP won power on the strength of winning the most seats in both Edmonton and Calgary, upsetting the traditional political divide. The NDP dominated Edmonton, taking every seat in the city by 4,000 votes or more. In Calgary, massive vote-splitting between the PCs and Wildrose allowed the NDP to take 15 seats. After only one term, however, the NDP was turned out of office in 2019 by the United Conservative Party, a merger of the Tories and Wildrose under the leadership of Calgarian and former federal cabinet minister Jason Kenney. This election saw Alberta's traditional political divide reassert itself. The UCP took all but three seats in Calgary, while the NDP held on to all but one seat in Edmonton.
