Elizabeth Warren keeps her dodge going, declining to meet with a group of Cherokee women who travel to Boston to ask about her claims to being of Cherokee descent. Warren, the Democratic candidate for US Senator from Massachusetts, cited those claims to advance her academic career at Harvard University and the University of Pennsylvania.  If Warren can legitimately prove her Native heritage, it’s time for her to do so. Otherwise, she’s a fraud and apologies are in order — not only to these Cherokee women, but also to the voters of Massachusetts and the universities she duped.
