States that have already broadly expanded health care coverage are pushing back against the Senate overhaul bill, arguing that it unfairly penalizes them in favor of states that have done little or nothing to extend benefits to the uninsured. With tax revenues down and budgets breaking, the states — including Arizona, California, New Jersey, New York and Wisconsin — say they cannot afford to essentially subsidize other states’ expansion of health care. The bill passed by the Senate on Thursday would move toward universal health insurance coverage in large part by expanding Medicaid, a program whose costs have traditionally been shared by the states and the federal government. But the roughly 20 states that have already expanded coverage in some form will pay a greater proportion of their new Medicaid costs under the bill than those states, largely in the South, that until now have covered relatively few of their poorest residents.The Kaiser Family Foundation has data on state Medicaid programs.
