Ten candidates vying for the 2020 Democratic presidential nomination took the stage Thursday night in Houston for the third round of debates. Unlike the previous debates, which took place over two evenings, only one night was needed to feature all who qualified for the showdown.

Julián Castro said Joseph R. Biden Jr.’s health plan would not cover enough of the nation’s uninsured population and would not automatically enroll people who were eligible.

WHAT Mr. Castro SAID:

“I also worked for President Obama, Vice President Biden, and I know that the problem with your plan is that it leaves 10 million people uncovered.”

Later, he added, “The difference between what I support and what you support, Vice President Biden, is that you require them to opt in, and I would not require them to opt in — they would automatically be enrolled.”
