Mr. Sanders was quick with his retort.

Sanders: You’re wrong.

Right now we have a dysfunctional health care system. Eighty-seven million uninsured or underinsured, 500,000 Americans every year going bankrupt because of medical bills, 30,000 people dying while the health care industry makes tens of billions of dollars in profit. Five minutes away from here, John, is a country called Canada. They guarantee health care to every man, woman and child as a human right. They spend half of what we spend and, by the way, when you end up in a hospital in Canada, you come out with no bill at all.

Health care is a human right, not a privilege. I believe that. I will fight for that.

Tapper: Thank you, Senator Sanders. Congressman Delaney.

Delaney: Well, I’m right about this. We can create a universal health care system to give everyone basic health care for free, and I have a proposal to do it, but we don’t have to go around and be the party of subtraction and telling half the country who has private health insurance that their health insurance is illegal. My dad the union electrician loved the health care he got from the I.B.E.W. He would never want someone to take that away. Half of Medicare beneficiaries now have Medicare advantage, which is private insurance or supplemental plans. It’s bad policy to underfund the industry, many hospitals will close and it’s bad policy.

Tapper: Thank you, congressman. Senator Sanders —

Warren: My name was also mentioned in this.

Tapper: We’re going to come to you in one second. Let me go to Senator Sanders right now. Senator Sanders?

Sanders: The fact of the matter is, tens of millions of people lose their health insurance every single year, when they change jobs or their employer changes that insurance.
