Laporta spins a fairly unconvincing study he commissioned as being an endorsement of a separate state for Catalunya. Only 47% of the people were in favor of their "own state", which is pretty low considering that he was able to set the wording of the question.
One interesting result from the study was that 38% of people consider themselves equally Catalan and Spanish. 26% were more Catalan than Spanish, and 6% more Spanish than Catalan. Only 27% considered themselves exclusively Spanish or exclusively Catalan.
This means that 70% of the population considers their cultural identity a mix between Catalan and Spanish.
That pretty much matches my experience, where conversations in groups of natives tend to switch back and forth between Catalan and Spanish, depending on what the speaker is most comfortable in or the language friends got to know each other in.
In any case, so far there's little danger of Laporta endangering CiU's march toward supremacy in the next election (according to La Vanguardia):
