I get the snark potential that attends anyone laying claim to a heritage on the basis of a great(x3)-grandma. If my mom is to be believed, I have about that much French blood, but I doubt I'd be claiming French ethnicity on that basis. What I find weird is all the vitriol it seems to arouse when Warren is doing an innocuous thing that many Americans like to do, which is to claim a pinch of first people's heritage. (I prefer the Canuck terms, First Nations or First Peoples, which seem more accurate than "native")
