Isn’t Alberta considered to be fairly conservative? I got talking to a guy from Alberta while vacationing a few years who described Alberta as “Canada’s Texas”.
Yes, I believe that Alberta as a whole, is the most conservative Province in Canada. That said, Edmonton, being a gubmint town (though with a strong, heavy industry base), tends to lean to the left. Its suburbs and environs tend to be right leaning. Rural AB is conservative. Calgary, except for ridings in the poorest part of town and around the U of C went conservative. The only other NDP win was on the west side of Lethbridge where, you guessed it, the university is located.
