It has been argued by some that parties such as Social Credit and Alberta Alliance could, with sufficient support, possibly threaten the now-traditional Progressive Conservative dominance in the province despite the much greater levels of support currently attained by parties such as the Liberal and New Democratic parties. The basis for such an argument is that both Social Credit and Alberta Alliance would most likely to compete for the "rural vote"- traditionally PC heartland. However, this has so far failed to materialize despite the promising showings by both parties in a number of ridings in recent elections.
