Final answer:
In states that do not expand Medicaid under the ACA, there will be a limited number of people eligible for Medicaid coverage, making it more difficult for certain poor citizens to access healthcare coverage.
Step-by-step explanation:
In states that do not expand Medicaid under the ACA (Affordable Care Act), there will be a limited number of people eligible for Medicaid coverage. The ACA offered an incentive for states to expand Medicaid, which would grant public medical insurance to more low and moderate-income citizens. However, some states, particularly those with significant Republican majorities in the conservative Midwest and South, have chosen not to expand Medicaid. As a result, in these states, it can be more difficult for certain poor citizens to access healthcare coverage. The Medicaid expansion would have extended coverage to more people, ensuring that a larger number of uninsured Americans could receive health insurance.
