Hah, I don't think anyone would disagree with you if your thesis here is "most people are generally uninformed". That being said, technically speaking yes, it probably was a different set of people polled, just considering how the nature of polling works! What you're not understanding though is that people actually seem to separate the content of the leak with the act of the leak. All it takes is a quick Google of "NSA spying program polling" to see polls affirming that hypothesis (folks disapprove of Snowden, but also heavily disapprove of the NSA spying program). Snowden himself has been known to beg folks during his interviews to stop caring about him or what he did, and focus on the content of the information he released, and I'd agree. So what if folks don't like Snowden?
