Donald Trump said he ideally would want the United States to have a single-payer healthcare system such as that in Scotland or Canada, but it wouldn't work in the U.S. because of state borders.

"I want to see a private system without the artificial lines with every state," Trump said during the Fox News GOP primary debate. "If I am negotiating in New York or California I have one bidder."

Trump then pivoted to a broad attack on his nine counterparts in the debate and politicians in general.

"The insurance companies are making a fortune because they have control of the politicians," said the businessman, who is currently leading in the polls for the GOP nomination.
