I'm relatively well versed in "the divide" so to speak. But I'm trying to understand what you mean by the Plymouth and Jamestown split as it relates to our modern country today.
It seems like both the spirit of Plymouth and Jamestown are inside the big tent of the Republican party today. But that doesn't sound like what you intended it to mean. Or maybe it is?
That's the part I'm curious about; who is Plymouth and who is Jamestown in 2025 in your eyes?
Plymouth is harder to identify. It's not just the Puritans at Plymouth, nor exclusively New England. It's merely everything that came with the second colonization. The Dutch are a foundational part of Yankeedom. In fact, New York should probably be considered more foundational than Plymouth. You would be right to identify Jamestown with the modern GOP. Traditionally it was represented by the Democratic party, but I assume you're familiar with that.
I should note these geists extend far beyond legitimate political guise.
