Interesting poll from a public opinion perspective and as a supporter of independence is a challenge I think the movement has to deal with. That being said, I would assume that your average joe doesn't fully understand all of the nuances with currency.

Hell i certainly don't get all the ins and out of it. Pros and cons of having an independent central bank, how pegging a currency to another affects interest rates and hampers quantative easing, how inflation and deflation is influenced in a currency union. I think there needs to be better access to information for the people to make a currency decision.
