Sen. Elizabeth Warren, who says she’s not running for president in 2020 but you knooooow she’s running for president in 2020, has big problems.

She’s got a nickname from President Trump — and NO ONE lives through a nickname from President Trump. Not former Sen. Al “Frankenstein,” not about-to-be-former Rep. Jeff “Flakey,” not former GOP candidate “Low-Energy” Jeb Bush, not even former Democratic presidential nominee “Crooked” Hillary Clinton.

Mr. Trump has dubbed Ms. Warren “Pocohantas.” And that’s a big problem.

The Massachusetts Democrat has long claimed to be of Native American descent, but when she was asked on Sunday if she’d take a DNA test to prove her heritage, she balked — big time. “I know who I am. And never used it for anything. Never got any benefit from it anywhere,” Ms. Warren said of her ancestry on NBC’s “Meet the Press.”
