The nationalist party Esquerra Republicana has been the most voted force in Barcelona. However, the independence movement as a whole barely reaches 39% in Barcelona. In fact, the independence movement has fallen sharply in Barcelona, going from 18 to 15 councilors in four years (out of a total of 41). The non-independentist forces rise from 23 to 26 seats, with the peculiarity that the parties that oppose secession go up from 12 to 16, surpassing the nationalist parties by themselves. In fact, Esquerra has only won the elections because the nationalist vote has been concentrated and the constitutionalist is dispersed.
Especially relevant is the case of the PDECAT, which can barely claim a third of the nationalism, and the CUP is outside the Barcelona consistory and most of the consistories of the area included in the concept "Tabarnia", which includes the coastal area of Barcelona and Tarragona and it is structured around the large municipalities.
In this area, the so-called "red belt" has revalidated its color (socialism), with Hospitalet del Llobregat being the main bastion of socialist constitutionalism, with Santa Coloma, Sant Boi, Sabadell, Esplugues, Gava and Sant Vicenç dels Horts (Junqueras' hometown) among many others.
Badalona has also been awakened constitutionalist, but under the banner of the Popular Party of García Albiol, while in Castelldefels the PP is also the first force, although the sum of the PSC and the populist "commons" can evict it.
Outside of Tabarnia, the small Catalan municipalities are subject to the dictatorship of fear. This means that in most of them it's indifferent how many constitutionalist voters there are, because they have no one to vote for, since there aren't constitutionalist majors. They are afraid to participate.
On a national scale, the debacle of Podemos is widespread. The "commons" throughout Spain recede dramatically. The losses of their two biggest strongholds (Madrid and Barcelona) are mortal wounds, and those wounds spread to the peripheral nationalisms with which they keep so much complicity.
As vaccinated by the ravages caused in Catalonia by nationalism, the Galicians have made the Tides sink, the constitutionalist force Navarra Suma has expelled the nationalism of Navarre (one of the few occasions in which Ciudadanos has shown that adding can go well), and in the Balearic Islands the nationalists are now irrelevant, (which could result in the disappearance of the current laws of linguistic discrimination).
However, the more moderate nationalisms are reinforced: This is the case of the PNV, more focused on scratching budgets to the government of Madrid, or Compromís, far from rupture positions. In fact, the growing presence of Esquerra Republicana in large municipalities of Barcelona has to be understood more as a compaction of the independence movement to less disruptive positions to the detriment of the PDECAT (which only has the consolation of beating Esquerra in Europe, where Puigdemont and Junqueras would be the faces if they did not finish stopped and suspended respectively) and of the almost extinct CUP.
