Vermont Sen. Bernie Sanders said this week that he plans to use the 11th Democratic debate to press front-runner Joe Biden on a series of liberal policy issues.

Mr. Sanders acknowledged Wednesday, after a set of losses in key primaries the night before that he was losing what he called the “debate over electability” to Mr. Biden. But he said if the former vice president hopes to win over his liberal supporters, he needs to sell them on his plans for health care, student loan debt and more.

Here are five of the questions Mr. Sanders said he planned to ask and a comparison of what the two Democrats have said on each issue in past debates.

Health care and Medicare for All: “What are you going to do to end the absurdity of the United States of America being the only major country on earth where health care is not a human right? Are you really going to veto a Medicare for All bill, if it is passed in Congress?”

Biden in Feb. 7 debate: “My proposal gives you a choice. You’re gonna be covered. You have Medicare if you want it, you turn up, we’re gonna restore all the cuts that they made in Obamacare. We’re gonna reduce drug prices, reduce prescription prices, reduce copays, etc. And it costs a lot of money, it costs $750 billion over 10 years…Bernie’s plan costs double, double what the taxpayers are paying for every single program we spend on in the United States of America.”
