A lot of actors go the conservative route. Jerry Doyle from B5 ran in a race as a Republican. A lot stay in the closet politically as it impacts their work opportunities. We definitely saw this with Sorbo. The guy from Growing Pains also had trouble getting roles. His sister moved on from Hallmark to GAC. The guy from the Passion of Christ actually lucked out with Person of Interest. There is definitely a polarization going on in media these days.I'm still struck by the coincidence that Kevin Sorbo was Dean Cain's runner-up for the role of Superman in Lois & Clark, and they both ended up following parallel career/ideological paths taking them about as far from Superman as you can get.
And if you go back in time for science fiction writers, there are a lot of conservative science fiction writers as well.
I finished Club Dumas, and it was free of political stuff. It was a nice take in the genre space of Da Vinci Code, but it was tied to the Three Musketeers. I enjoyed it, and I'd recommend it.
