The Fox-led campaign to pressure GOP governors to decline the Affordable Care Act's Medicaid expansion has left 5.7 million people uninsured who could have gained coverage under the law. In 2012, the Supreme Court ruled that states could decide whether to expand Medicaid eligibility to all adults living below 133 percent of the federal poverty line, under a provision of the ACA which would provide federal funding for the expansion. Immediately following the ruling, Fox News began a campaign to convince Republican governors to turn down the funding and refuse to expand the program.
