LINSEY DAVIS: This is now your third time running for president. you [Trump] have long vowed to repeal and replace the Affordable Care Act, also known as Obamacare. You have failed to accomplish that. You now say you're going to keep Obamacare. Quote, unless we can do something much better. Last month you said, quote, we're working on it. So tonight, nine years after you first started running, do you have a plan and can you tell us what it is?
