Doesn't match my experience. In fact, it's the exact opposite. The majority in my smoking circles here in ATL are younger, male, black, urban, and politically left -- beyond the weight of the general demographic. A surprisingly large number of sisters in the in the mix too. Can't speak to other countries, I'm not that well-traveled, but the popularity of cigars in the U.S. has grown beyond the stereotype since I started smoking in the 90's. My guess is that when it comes to cigars it's all tied more to profession/vocation, income level, social consumption preferences etc. than conformity to political stereotypes.
As for CC versus NC though, I do see greater interest in CCs among white males than any other group, regardless of political leanings.
Around here, guessing the make up is a fool's errand. Whatever triggers comments that reveal political leanings can only be measured by those of us that are willing to engage. Nothing else. And what constitutes right, left or centrist depends on too many subjective factors to be all that meaningful. I can tell you from personal experience that some here identify as more left or right leaning than they really are from a true ideological standpoint.
