Jaén's Socialist stronghold crumbles amid grievance sentiment and regional neglect

In March 2021, thousands of vehicles formed a convoy heading toward Despeñaperros, a mountain pass marking Andalusia's northern gateway. The drivers were from Jaén, and they had come to make a point at the region's front door: their province was being systematically neglected and disrespected by the institutions that governed it. The anger had crystallized weeks earlier when the national government, with the regional government's approval, announced that a major military logistics base—part of a broader defense infrastructure plan called Colce, worth 1.6 billion euros and expected to create 3,000 jobs—would go to Córdoba instead. Jaén had assumed the installation was theirs. The decision felt like a betrayal.

A year later, in the 2022 regional elections, that accumulated resentment produced a political earthquake. The Socialist Party, which had dominated Jaén for decades and had long boasted of its strongest electoral performance anywhere in Spain, lost its grip on the province for the first time. The People's Party won six of the eleven parliamentary seats available in Jaén. The Socialist stronghold had crumbled. Polls suggested the next election, scheduled for May 17, 2026, could make things worse for the PSOE, with projections showing the PP gaining another seat and the Socialists losing one more.

The scale of the shift was hard to overstate. There had been a time when Jaén was the Socialist Party's granary, reliably delivering at least seven deputies to the regional parliament. The province had wielded real influence in the Andalusian government itself; in some administrations, Jaén had sent as many as four regional ministers to the cabinet. Those days seemed distant now. The party that had built its identity on representing working people in this industrial and agricultural region was watching those voters walk away.

To try to salvage the situation, the government moved quickly. It announced that Jaén would receive the Cetedex—a Technology Center for Development and Experimentation, promoted by the Defense Ministry, with an investment exceeding 220 million euros and expected to generate around 2,600 jobs. Paco Reyes, who had led the provincial government for fifteen years and was now running as the Socialist candidate for the May election, called it a transformative project that would put Jaén on the map of the defense industry. More than 140 companies had already expressed interest in locating nearby. The first phase would be ready by 2028. But Reyes also criticized the regional government for its indifference to the project, suggesting that even this consolation prize had not received the backing it deserved.

The deeper problem was structural and long-running. Jaén consistently ranked last among Andalusian provinces in public investment. Its income levels lagged. Its infrastructure had been systematically dismantled over decades—the railway network had been gutted, and when the high-speed rail line was built to Granada, it bypassed Jaén entirely, even though the province lay directly on the Madrid-Granada axis. These were not abstract grievances. They were visible every day in the form of projects that never materialized, in young people leaving for cities with better prospects, in a province that was literally shrinking. In the past decade alone, Jaén had lost more than 40,000 inhabitants. It was the only Andalusian province whose population had declined compared to where it stood fifty years ago.

Sociologists and political scientists who studied the region saw the shift as part of a broader pattern. Felipe Morente, a sociologist who had coordinated a history of Andalusian sociology, observed that working-class voters were abandoning traditional parties in search of protection—a hunger that was feeding the rise of far-right populism. He also noted a deeper fracture: Andalusia was not one region but several, moving at different speeds, and the dominance of Seville in regional politics was becoming more visible and more resented every year.

Into this opening stepped Jaén Merece Más—Jaén Deserves Better—a regional party born from the same wave of territorial grievance that had produced similar movements in other neglected provinces like Teruel, Soria, and Ávila. In 2022, the group had come within 3,000 votes of entering the regional parliament. Now, in 2026, its young candidate, Luis García Millán, an engineer, was running a campaign that consisted largely of photographs of himself standing next to life-size cardboard cutouts of the regional and national Socialist leaders, positioned at sites where long-promised infrastructure projects—a tram system, a railway, health and justice centers—remained perpetually unbuilt. García believed he would enter parliament and become decisive in the next government, though the polls did not support him. The party's strength—its ability to appeal across ideological lines—was also its weakness. Voters attracted by the grievance narrative might feel betrayed if the party ended up compromising with either major party, as it had already done in several municipal governments.

What almost everyone in Jaén agreed on was that the next regional government needed to actually execute its budget and deliver on the infrastructure projects that had been promised for years. Bartolomé González, head of the provincial business association, made the point plainly: the province needed a government committed to real investment and to correcting the territorial imbalances that had left Jaén at the bottom of nearly every indicator. It had been twenty years since the last serious attempt—a plan called Activa Jaén, approved in 2006 under Prime Minister José Luis Rodríguez Zapatero, with 1.3 billion euros in supplementary investment spread across multiple years. That plan had dissolved almost as soon as it was implemented. Since then, Jaén had been in demographic free fall. The Cetedex represented hope, but it would not be ready until 2028, and by then, the province might have lost thousands more people.
