Participants in the two big Republican party presidential debates held Thursday focused only briefly on health care, but some candidates talked more about the issue than others.
Donald Trump, a real estate developer, took a question on reports that, in the past, he seemed to favor a government-run, single-payer health care system.
John Kasich, the governor of Ohio, was asked about his decision to take Patient Protection and Affordable Care Act (PPACA) Medicaid expansion money.
Producers at Fox News broke the event into two parts: a prime-time debate for 10 candidates, and a debate held earlier in the evening for six other candidates.

Two of the candidates who appeared during the prime-time debate, Ben Carson and Rand Paul, are medical doctors. Carson is a brain surgeon, and Paul is an eye doctor. The moderators mainly asked Carson about foreign policy and Paul mostly about non-health issues, such as his views on Israel and on data privacy.
For details about what Trump, Kasich and other candidates said, read on.

Donald Trump
Brett Baier asked Trump to discuss reports that, 15 years ago, Trump called himself “a liberal on health care” and promoted a shift to a Canadian-style single-payer system.
“Why were you for that then and why aren’t you for it now?” Baier asked.
Trump said that, in the past, he supported a shift to a single-payer system because that approach has worked in Canada and in Scotland. In the United States, “it could have worked in a different age, which is the age you’re talking about here,” Trump said.
Trump said that, today, he’d like to see a “private system without the artificial lines around every state.”
Trump, a real estate developer, said he has a big company with thousands of employees in multiple states. “If I’m in negotiating in New York or in New Jersey or in California, I have, like, one bidder,” he said. “Nobody can bid. You know why? Because the insurance companies are making a fortune because they have control over the politicians. Of course, with the exception of the politicians on this stage. But they have total control over the politicians. They’re making a fortune.”
Getting rid of the artificial lines separating each state’s insurance market from the others would leave the market with great plans, Trump said.
“And then we have to take care of the people that can’t take care of themselves,” Trump said. “I’ll do that through a different system.”
At another point, Trump said the country has to end PPACA.

John Kasich
Moderator Megyn Kelly asked Kasich about his decision to take PPACA Medicaid expansion money, and reports that Medicaid expansion has cost $1.4 billion more in the state than originally expected.
