"Hillary Clinton and Tim Kaine want more of the same," Pence said during the debate, which took place at Longwood University, in Farmville, Virginia, and was broadcast over television and streamed live on the Web by PBS NewsHour many other news organizations.

"Hillary Clinton and Time Kaine want to build on Obamacare," Pence said. "They want to expand it into a single-payer program. And for all the world, Hillary Clinton thinks Obamacare is a good start."

If Donald Trump becomes president, he will repeal the ACA "lock, stock and barrel," Pence said.

At another point, Pence mentioned social issues while talking about abortion.

"A society can be judged by how it deals with its most vulnerable," Pence said. "The aged, the infirm, the disabled and the unborn. I believe it with all my heart."

Kaine did not talk about the ACA or the uninsured during the debate.

He did say that Clinton had helped create the Children's Health Insurance Program, a program that helps low-income and moderate-income children get health coverage.

After the Sept. 11, 2001, terrorist attacks on the World Trade Center complex in New York and on the Pentagon in Washington, Clinton "worked across the aisle ... to get health benefits for the first responders who bravely went into the towers and into the Pentagon," Kaine said. "She worked to get TRICARE [military] benefits for National Guard members... She has a track record of working across the aisle to make things happen."

Kaine said Pence has favored privatizing Social Security.

Pence said that, in connection with Social Security, the Trump campaign has stated that, "We're going to meet our obligations to our seniors. That's it.... We've said we're going to meet the obligations of Medicare. That's what this campaign is really about."
