Massachusetts Sen. Elizabeth Warren slammed her Democratic primary rivals over their healthcare plans — or lack thereof — during Wednesday night’s debate.

“Mayor Buttigieg really has a slogan that was thought up by his consultants to paper over a thin version of a plan that would leave millions of people unable to afford their health care,” she said about the former South Bend, Indiana mayor.

“It’s not a plan, it’s a PowerPoint.”

Warren, who supports “Medicare for All,” hit Minnesota Sen. Amy Klobuchar even harder.

“And Amy’s plan is even less — it’s like a Post-it note, ‘insert plan here,’ ” she chided.

Warren’s opponents seemed taken aback by the attacks.

“I’m more a Microsoft Word guy,” Buttigieg quipped.

Klobuchar simply tried to give off some Minnesota charm.

“I take personal offense because Post-it notes were invented in my state,” she said.
