But if the best argument against Warren is her bad idea to try and capitalize on family history associated with Native Americans -- those against her are in big trouble.

She will rise or fall on her policy concerns and ideas. Time spent arguing about her misplaced reliance on family heritage is going to be irrelevant other than for cute jokes at the water cooler.
