Answer
Obamacare, also known as the Affordable Care Act, was replaced by the American Health Care Act, which was passed by the House of Representatives in 2017. Joe Barton, a Republican representative from Texas, voted in favor of the American Health Care Act, which would have repealed and replaced Obamacare. However, the American Health Care Act was not passed by the Senate, so Obamacare remains the law of the land.
