Here he is in a primary debate:
Q: Senator Rubio, you said that Mr. Trump thinks part of ObamaCare is pretty good. Which part?
RUBIO: The individual mandate. He said he likes the individual mandate portion of it; I don't believe that should remain there. We need to repeal ObamaCare completely and replace it with a system that puts Americans in charge of their health care money again.
TRUMP: I agree with that 100%, except pre-existing conditions, I would absolutely get rid of ObamaCare. I want to keep pre- existing conditions. It's a modern age, and I think we have to have it.
Q: The insurance companies say is that the only way that they can cover people with pre-existing conditions is to have a mandate requiring everybody purchase health insurance. Are they wrong?
TRUMP: I think they're wrong 100%. Look, the insurance companies take care of the politicians [and vice-versa]. The insurance companies are making an absolute fortune. Yes, they will keep preexisting conditions, and that would be a great thing.
You tell me. Where has he evolved?
