Ideological Divergence and Issue Convergence

This article explores the role of nationalism in paradiplomacy, the phenomenon of sub-state entities engaging in international affairs. In regions characterized by strong nationalist movements, paradiplomacy is utilized by regional actors to project a minority identity distinct from that of the majority centre. Quebec has sustained the world’s most advanced case of paradiplomacy, despite wholesale alternation between two ideologically divergent parties, the sovereigntist Parti Québécois (PQ) and the federalist Quebec Liberal Party (QLP). This article proposes party competition for issue ownership as a causal explanation of this convergence. The central argument put forth is that regional parties are galvanized by a nationalist electorate to take stances on international relations which promote their electoral competitiveness to voters vis-à-vis rival parties. The greater the emphasis a party places on itself as the most capable “owner” of the issue of the region’s international interests, the greater its commitment to paradiplomacy will be.
