Spain is a country where the nationalist cleavage has a fundamental importance to understand the party systems and the dynamics of electoral competition in some Autonomous Communities. This article analyzes the electoral bases of the main regionalist parties in Spain and, specifically, it focuses on the electoral bases of Canary Coalition (CC). Despite its importance at the regional level, this party has received little attention by the academic literature. This article confirms the idea that CC is a party able to mobilize an electorate whose preferences are for a more decentralized territorial organization than the current one. However, the key finding is that, unlike what happens with the main regionalist parties in Spain, the identity associated with the Autonomous Community is not an explanatory factor of the vote for CC, what shows that the Canarian identity is not politically activated.
