Liz Warren was born in Oklahoma to a poor family. There is a much higher percentage chance that she carries Indian Blood in her than not being born there. My Mother and Grand Mother were born there as well and I carry some Cherokee Blood. Not enough to cash in for the big bucks a 1/8th blood can but it's closer to a 1/64th. It doesn't take many generations to get it down that far. This is where MOST of us in our 60s and older are that have roots back to Oklahoma.
I am treated like a Brother by the Sioux, Navajo and Utes with as little indian blood as I have. I am called Brother and always have been. The only tribe or nation that won't do that is the Cherokee since it's a financial deal for them to claim that I am not of their heritage. They claim my heritage is probably Choctaw. What's funny is, I can't follow my Cherokee heritage back very far because it stops quickly. But if I follow my white side, it leads back to an Indian Agent in the Cherokee Strip who was married to a Cherokee Squaw who is in the chain. He was brought in because he was married to her. The old Indian Agent was ripping off the Tribe, causing them to starve and worse and the Tribe killed him. So they brought in someone that the Tribe accepted. Today's Businessmen in the Cherokee Nation do not accept them and claim she was Choctaw. (actually they hint at it). My Great Grand Mother was born in that Trading Post.
So the Indians and Native Americans don't have a problem with this. But you rightwing nutjob whiteys do. What's the matter, you don't think a half breed should ever be President?
