They tried to give me a survey once I told them who I was, but they wanted me to tell them my Colorado Voter status as the first&second question before moving on to questions about "global warming", and I told them I wouldn't answer the first two so move on to the others, but they refused and hung up. So I think they're a scam too, if only because they didn't care about getting as much info as possible for their "survey".
