His plan is for getting rid of Obamacare, dropping the borders for Health Insurance competition to make it more competitive, allow for Health Savings Accounts and conceptual deals with charities, hospitals, etc. to take care of indigent, probably similar to Medicaid which already exists. Not universal health care.
Yeah that would probably lower the cost of insurance, but what about tort reform? Also Ted Cruz explained the exact same plan, adding that he would make healthcare portable, not linked to your job, so that you can take it where ever you go. Cruz also explained this plan months ago, long before Trump had anything but a germ of an idea of what he wanted to do with the entire mess beside repeal of ObamaCare.
