What's Hawaiian conservatism like?

[Del Tachi]

I've read before that whites in Hawaii come disproportionately from Southern backgrounds, presumably because of its large military population. I'd imagine they constitute part of the Republican vote in the state.

Presumably because Hawaii had a system of plantation agriculture much like the Antebellum South, you mean?  I'm a tenth-generation Mississippian and have some family connections to Hawaii.  And I think active duty military tend to vote in their home state, not where they're stationed FWIW
