There are many without health insurance, but it doesn't mean that they are denied from receiving health care. Of course, many without health insurance may not get the full benefit of health care such as dental. However, they will receive health benefit. Medicaid in its verious forms, different names in different states, provides health care coverage to low-income families, and to the extend of illigal immigrants.
