European elections provide a snapshot of the penetration of parties and the tendencies of their electorate.
The PSOE stood firm against a strong offensive from the right, confirming its position as the main exception to European social democracy.
Regional disparities sketch a concerning picture for the PSOE, particularly in Madrid and Andalusia where the PP dominates.
There is also a noted reliance of the PSOE on Catalan and Basque votes to counterbalance the advance of the PP.
The PSOE still has work to do in terms of strengthening their territorial base, and the election results illustrate this challenge.
The PSOE's strategy may be effective in regions like Catalonia and the Basque Country, but it is counterproductive in other parts of Spain.
Conclusion: It is pivotal for the PSOE to develop a vision and project that are palatable and attractive to all of Spain's autonomies rather than depending on regionalized success.
