> I can reasonably extend the benefit of the doubt to Elizabeth Warren that she didn't know if she was actually some fraction Native American or not until the DNA test.

But she didn't claim to be 'some fraction Native American'. She said her race was 'Native American', just full-on 'Native American', on an official form.

And she claimed to be Cherokee in a book. That's even more bizarre of a thing to claim. No matter what anyone told her, she must have known she wasn't part of the tribe?

People say she's apologised, but she hasn't really said 'I'm sorry that I...' except that she's caused distress. What does she now admit she did? Lied? Stretched the truth? What does she see it as? What was going through her head. What would lead her to make such obviously ludicrous claims? Even if she did have one recent ancestor, which it turns out she probably didn't, it's still a nonsense claim that she is Native American and Cherokee.

Does she still think she's Native American? Will she describe herself as the first Native American president? If she doesn't, what does she say is the difference between now and when she filled out that form? That's what I'm missing - her explanation.

I'm a little bit Native American, according to my family. I have never claimed that my parents weren't allowed to get married because of their tribes, nor have I put Native American down as my race on a college application.

Warren found a politically convenient fractional truth and exploited it.
