Soon after leaving Parliament, Harper and Tom Flanagan co-authored an opinion piece entitled "Our Benign Dictatorship", which argued that the Liberal Party only retained power through a dysfunctional political system and a divided opposition. Harper and Flanagan argued that national conservative governments between 1917 and 1993 were founded on temporary alliances between Western populists and Quebec nationalists, and were unable to govern because of their fundamental contradictions. The authors called for an alliance of Canada's conservative parties, and suggested that meaningful political change might require electoral reforms such as proportional representation. "Our Benign Dictatorship" also commended Conrad Black's purchase of the Southam newspaper chain, arguing that his stewardship would provide for a "pluralistic" editorial view to counter the "monolithically liberal and feminist" approach of the previous management.
