PSOE loses Andalusia for the first time (2018)
After 37 years of PSOE rule, a PP-Ciudadanos coalition formed in Seville with Vox support. PSOE's Susana Díaz won the most seats but could not build a majority. The result broke the assumption that Andalusia was structurally Socialist.
Juanma Moreno became the first PP president of Andalusia in January 2019.
PSOE never recovered its rural southern machine. The 2018 result is now seen as the start of a slow national realignment.
The 2026 vote shows the 2018 break was not a protest but a durable change. PSOE's southern base has eroded further, not snapped back.
