Pedro Sánchez's PSOE is experiencing a significant territorial decomposition.
This decomposition was evident in the regional elections on 28-M and became even more evident in recent elections.
In the last four years, the PSOE has lost seats in 12 of the 17 Autonomous Communities, and has lost power in six of them. It now presides over only three.
The PSOE's move towards nationalism has had a high cost on the regional establishment of the party.
The party's leadership, headed by Pedro Sánchez, has taken a direction that has disjointed the country.
There is a growing perception within the PSOE that Sanchez might not politically survive after the June European elections.
Conclusion: The fall of PSOE is evident, and with it, a political and territorial crisis in Spain has been generated. Pedro Sánchez's position is becoming increasingly compromised, whilst the role of PP in this context becomes crucial for the stability of the State.
