^ Ya it's getting bigger which helps, and the cowboy culture of Albertan identity is starting to show cracks. But immigrants are also frequently targeted with this type of messaging and convinced to vote against their own interests (see Jason Kenney and NE Calgary).

Jared Wesley has done fascinating research on Alberta identity btw. Even if it doesn't represent the average Albertan anymore, cowboy culture is a strong and enduring image.
