Analysts and journalists were divided on the causes behind the PSOE 's downfall . Some attributed it to discontent with the Sánchez government and his policy of seeking the parliamentary support of pro-Catalan independence parties in the Congress of Deputies after the vote of no confidence which ousted Mariano Rajoy from the central government , which would have prompted a high turnout from right-wing voters . Others , on the other hand , attributed it mostly to Susana Díaz 's ruling style in Andalusia : high unemployment and rampant corruption , discontent with her government 's management of the education and health services in the region , her role in the ousting of Pedro Sánchez in 2016 , the subsequent PSOE 's abstention to allow for Rajoy 's investiture and her foiled attempt to become PSOE leader in 2017 were also said to have played a major role in the low PSOE voter turnout , together with a deep disenchantment and fatigue with the PSOE 's 36-year spell in the Regional Government of Andalusia . Concurrently , the fragmentation within the centre-right to right-wing electorate was also noted as a remarkable event , as the PP 's decades-long , unquestioned dominance over such spectrum came to an end
