So, correct me if I'm wrong, but I have seen no reports of violence in Crimea.
That makes me think there must be some truth to the polls.
Plus, Forbes magazine, the news source, is pretty consistently Center-Right with its news, so I'd be surprised if they are 100% wrong on the facts.
Bottom Line - To a casually informed observer, Crimea looks like a lot better place to live than Ukraine.
On the other hand, the poll might be skewed because the respondents are afraid of being dragged to the street and beaten. And the notion of someone in that area trusting a pollster is amusing.
