The CEO, the department for opinion studies of the Catalan Government, has just published the results of the latest poll. It asks for the first time about what would voters do in a referendum of independence.
The results confirm what similar polls (like here) made in the last two years said, a clear win for Catalonia’s independence. 42.9% votes to yes, 28.2% no, 23.3% abstention and 4.4% doesn’t know. Meaning the yes would have a 60% support against a 40% for the no.
