ObamaCare gives states the option to expand Medicaid to cover all individuals below 138 percent of the federal poverty level, which is approximately $33,500 a year for a family of four. To encourage states to expand, the federal government agreed to fund 100 percent of expenditures for the newly-eligible participants until 2016, and then slowly decrease the match to 90 percent in 2020 and into the future.

Democratic and Republican governors alike are showing their penchant for “free” federal dollars by supporting expanded Medicaid roles in their state. Republicans governors—who often say they dislike Obamacare—are in many cases pushing their legislatures to expand Medicaid to take advantage of this windfall.

GOP Governor Bill Haslam in Tennessee announced that he would support Medicaid expansion. His administration promoted the plan by saying, “Insure Tennessee will leverage the enhanced federal funding which will pay for between 90 and 100 percent of the cost and in doing so will bring federal tax dollars Tennesseans are already paying back to the state.”

To help minimize the state’s contribution and maximize federal funding, Haslam decided to expand the state’s health provider tax. Under a provider tax, a state agrees to increase Medicaid reimbursements to the providers paying the tax, such as hospitals. The higher reimbursement level draws a higher federal contribution. So state politicians and hospitals win, but federal taxpayers lose.  

In this case, luckily, Tennessee’s legislature denied Haslam’s  expansion attempts.

Governor Mike Pence in Indiana is pushing for Medicaid expansion, dubbing the program “Healthy IN Plan 2.0.” Governor Pence received an “A” in our Fiscal Policy Report Card on America’s Governors last year for his tax-and-spending restraint. But his decision to expand Medicaid to include working-aged, able-bodied, childless adults sends a very different signal.

Governors Pence and Haslam aren’t the only two Republicans wanting to expand Medicaid. Wyoming Governor Matt Mead said that by rejecting Medicaid expansion the legislature is “rejecting $120 million dollars meant for Wyoming.” Governor Gary Herbert of Utah has saidthat Medicaid expansion allows “Utah [to bring] taxpayer dollars back to our state.” More than 10 Republican governors support Medicaid expansion, many using this same sort of rhetoric.

These governors justify their actions by claiming that it will return tax dollars to their states. But Medicaid spending is not a fixed pie. The more that each state expands its program, the more that the nation’s taxpayers will be hit.  Federal expenditures are funded based on the matching percentage. It’s not true to say that if Tennessee doesn’t expand, that the money goes to California. Instead, if Tennessee doesn’t expand, then the money isn’t spent and taxpayers keep more of their earnings.

As I’ve discussed before, expanding Medicaid is also a risky proposition for state budgets, which some Republican governors do not seem to understand. They boast their fiscal conservatism, but their recent actions on Medicaid expansion come at the expense of a larger burden on the nation’s taxpayers.
