Those who have Medicare are much more satisfied than those with private insurance.  Those who don't have Medicare are much more apt to buy into phony claims about the effect of public control.  Those who have Medicare know they have access to the doctor of their choice while those too young to use it believe phony claims that Medicare does not provide this and by
extension that government will interfere with their choices of health care.
