The odds are a bazillion to one that she hasn’t already taken a DNA test under another name and failed. If she was confident about her heritage, she would have taken and announced those results a long time ago. To me, this is absolute confirmation that she’s a liar and a phony. There is no way she would be offered as a Democrat Presidential candidate for 2020 if she refuses the test. If she did agree to a test, I would surely want to follow that sample from its taking to its reporting.
