Sen. Elizabeth Warren just refuses to stop digging. On Sunday, she actually tried to claim she took that DNA test to resolve her Native American ancestry because she wanted to rebuild Americans’ “trust in government.” Right.

“Confidence in government is at an all-time low,” she noted. “And I believe that one way that we try to rebuild confidence is through transparency.”

That is: “I took a DNA test because I am an open book. And it’s all out there. It’s on the Internet. Anybody can take a look. Because, at the end of the day, this isn’t about me. This is about what’s happening to working families.”

In fact, the whole thing isn’t “out there”: What she released is the report from her chosen expert, who concluded that the senator likely had a Native American ancestor six to 10 generations back. Cherokee Nation leader Chuck Hoskin Jr. hit her effort as “inappropriate and wrong.”

Nor does it remotely justify Warren’s claims, back when she was looking to jump-start her academic career, that she was Native American. (She ID’d as Native in the Association of American Law Schools directory, and went along with the law schools’ listing her as Native on federal forms.)

She has long sought to deflect the real debate into a discussion of her family legends about ancestry, which is beside the point.

Most important: Her whole DNA gambit is purely a bid to get this nagging problem off the table before she launches a White House run. This is no effort “to rebuild confidence is through transparency”: It’s a con.
