Which doesn't mean anything at all unless you want to explain how it applies here.
Warren grew up listening to her mother talk about "our native American heritage." Was it a mistake for her to list herself that way in some college publication based only on family lore? Perhaps. Then again, I can think of a few more serious political scandals than this, like all of them.
I seriously hope when she runs in 2020 that the right plays this up to the max, showing up at rallies with head dresses, tomahawk cops, etc. etc. If this is the best they can do, 2020 is already over.
Aside from the Warren and the college aspect, i think there is more to heritage than just DNA.
It's about culture and identity. Many Americans come from a mixed background, but I imagine most people pick out one of their lines as more defining than the other in terms of identity and heritage.
I have 16 great grandparents, but I really know only a few prominent ones and their background, which forms my background and family identity. Would this exactly align to DNA results? No.
I mentioned earlier I was some part Cherokee, and also learned I was part Choctaw. All told, DNA % was well into double digits. (Ancestry search also confirmed.) Family has some connection to this same region Warren is from, OK panhandle area (CO, OK, KS, TX). Perhaps it's more common in that area .
Don't make much of it, other than it's in the complex tapestry of a typical melting pot American background.
I do think Trump's mocking her as Pocahontas is both childish and a ham fisted attempt at racial denigration.
