Recent polls for the November 29 general election show EH Bildu narrowly ahead in Biscay with an estimated 25.9% of the vote and three seats, followed closely by PSOE at 25% for two seats and PNV at 24.7% for two seats, with PP securing the remaining seat. The contest remains tight because vote shares sit within one to two points of each other, and small shifts in turnout among nationalist and left-leaning voters can alter the seat distribution under the d'Hondt method. October surveys from the Basque government's Sociómetro captured EH Bildu's gains at the expense of declining state-left options, while PNV holds steady in its traditional stronghold and PSOE maintains competitive support. Any late campaign developments in the final three weeks could still reorder the leading positions before ballots are cast.
