Zapatero's PSOE wipeout (2011)
After the eurozone crisis and harsh austerity, PSOE under Alfredo Pérez Rubalcaba lost the general election by 15 points. PP won 186 seats and an absolute majority. PSOE took 110 seats, then its worst result.
Mariano Rajoy formed a PP majority government and pushed deeper austerity.
PSOE took eight years to return to power, and only with the help of new left and regionalist parties that had grown in the gap.
It is the closest national parallel for what could happen if the Andalusia pattern repeats nationwide. A long PSOE rebuild, not a quick rebound, is the historical default after a result this bad.
