Zionism is alive and well in protestant non-denom, non-credal Christian circles like Calvary Chapel, as well as some southern Baptist circles. I'll have to look up what "preterism" is.

Funny. It's not niche at all. Partial preterism is what's been believed for these two millennia. It doesn't need a special name. That's just part of Christianity. The "left-behind" view is the novel one.
You would think this would be common knowledge but American Christians became terribly confused in the last hundred years and are just finding their way back through younger generations.
