Alberta is more urban and diverse and with less regional polarization I could see more "liberal" tendencies emerging in Calgary and Edmonton. But in federal politics the Conservatives function as a sort of big tent "party of Alberta" that draws in the types of people that would be "blue Liberals" or populist NDPers if they lived in Ontario or BC (and these Albertans do vote for other parties in provincial elections).
How are "populist NDPers" analogous to "blue Liberals"? I thought the NDP is left of the Liberals on both economic and social issues.
