Sure, voters are used to politicians lying to their faces. That’s sad but true.

However, U.S. Sen. Elizabeth Warren this weekend raised that to an art form.

Asked in three TV interviews about the editorial request from the quite liberal and presumably friendly Berkshire Eagle that she submit to a DNA test to provide evidence of her alleged Native American ancestry, Warren instead repeated the oft-told tale of her parents’ meeting:

“My mother and daddy were born and raised in Oklahoma. My daddy first saw my mother when they were both teenagers. He fell in love with this tall, quiet girl who played the piano. Head over heels. But his family was bitterly opposed to their relationship because she was part Native American. They eventually eloped.”

That’s it. That’s her story and she’s sticking to it. It is, of course, a non-answer to the DNA question and the elopement part of the tale has long ago been disputed. Warren’s parents were married by the minister of the Methodist Episcopal Church in the next town over and the marriage was announced in their hometown paper days later.

“That’s the story that my brothers and I all learned from our mom and our dad, from our grandparents,” Warren insists. Her verbatim retelling is almost scary.

Moving on to the other Big Lie — this one also in the form of a non-answer to an entirely specific question.

“So look, I am not running for president of the United States,” she told NBC’s Chuck Todd on “Meet the Press.” “I am running for the United States Senate, 2018, Massachusetts. Woo-hoo.”

But when asked repeatedly if she will vow to complete that six-year term, she reverts to the rhetorical loop: “I’m in this fight, that’s where I’m focused.”

The NBC, CNN, Fox News blitz would seem to say otherwise. But why give a straight answer when obfuscation is her stock-in-trade.
