Sixty-seven percent of registered voters support allowing people under 65 to have an option to buy health care coverage through a Medicare program, while keeping private insurance options available, according to the Wall Street Journal/NBC news poll released Sunday.

The survey found 78 percent of Democratic primary voters said they support allowing people under 65 to have the option to buy health care coverage through a Medicare program.

A smaller percentage of Democratic voters, 63 percent, said they support a single-payer health care system that would eliminate private health insurance
