Yes, around 8% vote for nationalist parties. They don´t form a coalition so BNV and EUPV don´t get parlamentary representation in the Corts (the autonomical parlamentary chamber). It´s not that hard to understand. The one party that gets representation is Esquerra Unida, which has got a strong nationalist bloc in it, Esquerra ane País (the other main bloc inside the party being the communists). No one is misleading, friend.
