There's indeed an unfortunate contingent of far-right pagans who see their faith as a component of racial identity and can be quite deranged and militant about it, most of us are hippies, as one would expect from a people heavily defined by our love of nature. Demographic studies have shown that most American pagans are white, middle or upper-middle class, urban or suburban, and college-educated, which all points towards a solid Democratic lean in current alignments, and most pagan faiths besides the Nazi-flavored ones encourage libertarian social attitudes. However, as plenty of pagans such as myself also skew heavily left-wing and rather outside of the American Overton window, I'm sure there are plenty of third-party voters among us, mainly Green (as I tend to vote) but perhaps especially in some of the more explicitly politicized strains such as Reclaiming you'd find support for more radical groups such as PSL and their ilk. I'd be quite interested in doing more in-depth study on this topic.
I would assume Anarchism would be where most leftist Neopagans would find a home in. I’ve never heard of the PSL or any Marxist-oriented party attracting such a religious demographic; most of the time they attract Buddhists and second generation Muslims.
I’m more interested which strains of paganism vote as well. I assume the male-dominated followers of the Norse and Germanic religions lean R while Santa Muerte followers, when they do vote, vote overwhelmingly for the Green Party.
