Biden remains stubbornly on the national platter, congealing like day-old “Cold Omelets with Crab Meat,” the now-infamous dish Warren offered as authentic Cherokee fare in the cookbook “Pow Wow Chow,” back when she was climbing the political ladder as an authentic Native American Harvard law professor.

“You can’t call on Warren to drop out,” said a guy who’s been counting all the “Warren Has a Plan for That” signs sprouting in his progressive North Side Chicago neighborhood. “She’s a woman. And Democrats will need the white suburban woman vote in 2020.”

True, and I mean no disrespect to her, her gender or to the Democratic Party’s strategy to target that key suburban white female demographic through a relentless 24-7 media spin that’s been going on since 2016.

But the charade of representing herself as a Native American, and the catastrophe of her DNA test, turns off working-class families. Democrats need them too.
