Donald Trump feels that Obama care is "terrible" and should be replaced. He is strongly opposed to the affordable care act. He wants to work to "lower barriers for drug companies to enter the marketplace."
I don't think Donald Trump would do many changes to the "Obama Care" because too many people rely on it for their insurance. I think he would make it different not follow the same guidelines as the Obama Care he will not take away affordable insurance for the people that really need it. Trump's nominee will go into detailed paperwork to see what really needs the affordable health care and who's just getting the health care because they do not want to spend a lot of money on "official" healthcare.
