Real Clear Politics executive editor Carl Cannon said in an interview that aired Tuesday on "What America's Thinking" that the U.S. is headed toward adopting the idea that medical care is a human right.

"'Medicare for all' means we have gone in a place in this country where we think medical care, at least for catastrophic illnesses, for cancer, for other serious things, is a human right," Cannon told Hill.TV's Jamal Simmons on Monday.

"This is a relatively new idea, not only in this country but on this planet, and that's where the country's moving and I think that's what 'Medicare for all' stands for," he continued.

The proposal has been floated by potential and current 2020 Democratic contenders, including Sen. Bernie Sanders (I-Vt.) and former Housing and Urban Development Secretary Julian Castro, who announced his candidacy last week.

A Reuters–Ipsos survey last August found that 70 percent of Americans support "Medicare for all," comprised of 85 percent of Democrats along with 52 percent of Republicans.

Cannon went on to say that Republicans, who have tried and failed to repeal ObamaCare, need to come up with their own version of "Medicare for all" that fits in with their beliefs on health care.

"I think Republicans are coming along more slowly, but I think it's almost a consensus in this country," he said. "What the Republicans should do if they don't want 'Medicare for all' is come up with an alternative that has that goal."
