I've been following a few of the small political parties; the anti-nationalist Ciutadans aren't going to win a seat in the Barcelona city council, but they have a chance in several cities, including Figueres, Terrassa, Tarragona, Vilafranca, and Vilanova. The xenophobic Plataforma per Catalunya won three seats in Vic, and has a chance of winning representation in several places, like Olot, Tarrega, and Falset. The Partit Republicà Català, which ain't your mama's GOP but rather more independentista than Esquerra Republicana, has a chance of gaining representation in several cities as well.
