He has? Can you show me where he's said that?
What I have heard Trump say is that he (the federal government) is going to force states and insurance companies to open up borders for the purpose of purchasing insurance across state lines (at least that's how I understand that). He also explicitly said that Obamacare is going to be repealed and replaced; which I interpret as - it's going to be replaced with a federalized program/law. What is that going to look like? Why is the federal government responsible for making sure EVERYONE is covered?
Not everyone in the US. Vrai and I have said ad nauseam those who cannot provide for themselves.
