His anecdote refuted the point he was responding to, which inaccurately stated that only emergency care is covered. Medicaid covers long term care for poor people. (In 18 mostly southern states Medicaid doesn’t cover childless adults, but that encompasses a distinct minority of the population of poor people even in those states. In the other states Medicaid covers everyone below a certain income level). Most people who fall into the “went bankrupt from medical bills” category are ones who weren’t poor before the medical bills and didn’t qualify for Medicaid.
