Gallup editor-in-chief Mohamed Younis said in an interview that aired Thursday on "What America's Thinking" that most Americans want to see some change in the health care system.

"When you ask people, a majority of them actually want to see something change," Younis told Hill.TV's Krystal Ball on Wednesday, referring to a new Hill-HarrisX survey.

"A majority of people say there [are] either major problems or that the health care system is currently in crisis," he continued. "So there's appetite for change. There's majority support for the ACA [Affordable Care Act] in place, but over 40 percent of people want to see significant changes even to the ACA."

"So it's not clear. Folks are clearly saying the system is still sort of broken to some degree, but there isn't a lot of consensus around how to fix it in one way or another," he said.

The poll comes as 2020 Democratic presidential hopefuls decide how far they want to go in championing "Medicare for all," which would aim to provide health care for all Americans but would eliminate private insurance.
