Republican Left of Catalonia. As the name implies, they're Catalan separatists, and the only major party that was big enough for me to put into the poll. All of the other left-wing regionalist parties combined won't get Sanchez over the top, only ERC can do it, and there's a lot of problems with re-energising the secessionists in Barcelona. Hell, Puidgemont's party got 7 seats, more than was expected. On top of this, the regional elections are next month, and this will make a lot of people in Spain quite nervous.
