Gabriel Rufián, spokesperson for ERC in Congress, recently proposed that leftist nationalist and state parties should coordinate to avoid competition in provincial elections, aiming to improve electoral outcomes in the upcoming general elections. This suggestion has sparked debate among the parties involved in Sumar, with various reactions emerging. While discussions are generally positive regarding the idea, the Comuns party has expressed concerns about being overshadowed by nationalist parties in potential electoral lists and has emphasized its significant role in Catalonia's electoral landscape.

Ada Colau, leader of the Comuns, has made a case for the prominence of her party, highlighting that in the 2023 elections, Comuns-Sumar outperformed Esquerra in terms of votes. This context reveals a tension within the left regarding the collaboration Rufián has suggested, where parties are cautious about their local influence and representation. The left, while acknowledging the potential benefits of such coordination, is also wary of compromising their identities and electoral positions.

The complexities of this proposal underscore deeper issues in Spanish politics, particularly among left-wing factions. As they navigate their strategies for the next elections, balancing unity with individual party interests will be crucial, especially in a context where national and regional dynamics significantly impact political alliances. The outcome of this debate could have implications not just for Sumar but also for the broader leftist movement in Spain as they aim to consolidate power against competing right-wing forces.
