Through 2016, the federal government paid 100 percent of cost of Medicaid for the 700,000 Ohioans who gained coverage via the expansion. The federal share will taper to 90 percent in 2020, and remain at 90 percent thereafter. (This year, the federal share of the cost is 95 percent.)

Stats are readily available, by county, on the the number of Ohioans who gained Medicaid coverage thanks to expansion. But congressional districts are composed not only of whole counties, but (often) parts of counties. What follow are rough estimates of Ohioans benefiting from Medicaid expansion in some GOP-represented congressional districts. The estimates combine (rounded) totals of the number of Ohioans in each district’s counties whom Medicaid expansion covers – and (rough) estimates of the number of Ohioans who gained coverage in those portions of a district that consist of portions of counties.

First, statewide demographics: Of Ohioans Medicaid expansion covers, 71.5 percent are white; 24.8 percent black; and 3.7 percent Hispanic.

Ohio’s 6th Congressional District, represented by Marietta Republicans Bill Johnson, stretches from suburban Youngstown south to East Liverpool, then along the Ohio River all the way to the state’s southern tip. Rough estimate, but perhaps 51,000 of Johnson’s constituents have Medicaid coverage due to the program’s Ohio expansion.

Then there’s the 15th Congressional District, represented by suburban Columbus Republican Steve Stivers. From 50,000 to 53,000 of Stivers’ constituents likely gained Medicaid coverage due to Kasich’s expansion of the program; about 2,600 of those Ohioans live in Clinton County, home of Ohio House Speaker Clifford Rosenberger, a Clarksville Republican.

And in Republican Mike Turner’s 10th Congressional District, which includes Montgomery and Greene counties, and part of Fayette County, Medicaid enrollment totals suggest that 45,000 to 46,000 of Turner’s constituents would lose Medicaid coverage if Club Ryan rolls back the Medicaid program’s expansion. So might 44,000 residents of the 2nd District, represented by Cincinnati Republican Brad Wenstrup. His 2nd District reaches from the Cincinnati area up the Ohio River to western Scioto County.

True, Paul Ryan and company could seek to freeze rather than end Medicaid expansion. But a freeze would mean no more Ohioans could qualify for expansion coverage and, over time, the number of Ohioans who still had expansion coverage would fall. In Washington, that may be an applause line. In real-world Ohio, it’s anything but.

Republican Gov. John R. Kasich, to his credit, opted to expand Medicaid in Ohio, as the Affordable Care Act lets states do. By last fall, about 700,000 Ohioans had gained Medicaid coverage thanks to Medicaid expansion.
