In 2018 only about 17 states and the district have ACA exchanges.
Unsustainable ACA Exchanges continue to die as planned. The failure was supposed to cause Socialized single payer Healthcare based upon nasty European lines.
Obamacare wrecked a health care system that worked well for 90% of the population and replaced it with a health care system to cover the 10% who were uninsured or had pre-existing conditions.
In the end it helped neither and ended up making health insurance more expensive for everyone.
Obamacare is gone and no one will miss it.
