What errors do you imagine I made? Be specific, please.
If you want to point to an expert in genetics, who just happens to be a member of the Cherokee nation, I'd be happy to consider what he or she has to say on the topic. If, instead, you're just referring to the politicians who speak on behalf of that political unit, why would I care what they have to say on a scientific question like this? Keep in mind, we're not discussing whether or not Warren has political status as a member of that tribe -- she has never said she does. We're discussing whether she has Native American ancestry -- which, as you know, she does.
