How did Native Americans vote?

[Make America Grumpy Again]

I think Native Americans are more likely to vote against their state government due to oppression and lack of recognition/racism. Southern/Western Natives are more likely to be Democratic while Midwestern/Northeastern are more likely to vote Republican for similar reasons, which can explain why the Natives of The Dakotas are powerfully Democratic, while the Native areas of Oklahoma are a lot closer than the white areas. NC is an interesting contradiction to my claims though, as Trump increased on this group without NC flipping, but he did federally recognize the Lumbee tribe (well Obama did but Trump took credit). That area of NC is also socially conservative (Robeson county is only 1 of 2 NC counties to allow corporal punishment to be used in school) so it's probably more complicated than a political party being in power.
