A key provision in the Affordable Care Act (ACA) of 2010 provided federal funding for states to expand Medicaid coverage to individuals earning up to 138% of the federal poverty line. Currently, 33 states plus Washington, DC, have elected to expand Medicaid coverage, and others may soon follow suit. Polls suggest that Medicaid expansion is one of the more popular components of the ACA.1 Among the approximately 20 million individuals in the United States who newly acquired health insurance following the ACA, more than half received coverage through state Medicaid expansions.2
