The upcoming Basque Parliament elections could see the rise of the abertzale left, represented by EH Bildu, potentially toppling the PNV's supremacy.
Polls show a tie between the PNV and EH Bildu, both poised to secure 29 seats each.
The PNV has been showing a downward trend, while EH Bildu has been growing.
The PNV's declining support is due to management issues and problems within the Basque public health sector.
EH Bildu's growth is attributed to its pragmatic shift and programmes with a stronger social than national focus.
Three out of every four votes is expected to back parties supporting the Basque Country's independence, despite a decline in unconditional support for independence.
Pragmatism appears to prevail, with PSE and PP maintaining their results, while the divided left of Sumar and Podemos could be reduced to testimonial representation.
The elections mark a generational shift, with Iñigo Urkullu handing over the PNV's leadership to Imanol Pradales, and Pello Otxandiano representing a rejuvenation in EH Bildu.
Conclusion: The upcoming Basque Parliament elections are marked by a potential shift in political supremacy, with the emergence of EH Bildu alongside the decline of the PNV, with pragmatism and generational renewal as determining factors.
