> For example, starting in 2014, Medicaid (health care for the poor) was expanded to cover those earning under 138% of the poverty line (a perfect example of the confusing way in which assistance is determined). Many states chose not to expand Medicaid, so they will not receive additional federal funding for the program. States that did, however, will.

It's worth noting that the law as written, did not leave much of an option for the states to not expand Medicare. However, the law was gutted by the court system, so most of the right-leaning states chose not to expand it.
