Young Basques do not vote for the parties that are in power. They choose a nationalist ballot, preferably that ofEH Bildu or abstained.

Between 18 and 34 years the most supported party is EH Bildu. The average age of PP and PSOE voters is the highest: 60.1 and 57.9 years. In these age groups the votes for socialists and popular are very scarce (between 0% and 8.9%). For decades, when the name Rentería (39,200 inhabitants) was heard, the first thing that came to mind were burned containers and buses.
