In spite of the Affordable Care Act there are many people in our country without health insurance. "The remaining uninsured are primarily in the South and the Southwest. They tend to be poor. They tend to live in Republican-leaning states. The rates of people without insurance in the Northeast and the upper Midwest have fallen into the single digits since the ACA’s main provisions kicked in. But in many parts of the country, obtaining health insurance is still a problem for many Americans."
See: We Mapped the Uninsured.
The states with the lowest percentage of uninsured tend to be the ones that have expanded Medicaid coverage. However, it can be difficult for Medicaid patients to obtain health care, especially from specialists. See: Cherry Picking in the Aina.
It's hard to believe there are still so many health care unequalities.
