The Senate's secretly bipartisan health-care bill

The Senate bill’s plan to reform Medicaid by tying per-enrollee spending to medical inflation through 2025 and to consumer inflation thereafter was borrowed from a nearly identical 1995 proposal by President Bill Clinton. Indeed, the main difference between the Clinton proposal and the Republican one is that the Clinton proposal would have tied per-enrollee spending to growth in the gross domestic product. Historically, medical inflation has been higher than G.D.P. growth.

The Senate bill replaces the A.C.A.’s Medicaid expansion with a robust system of tax credits for which everyone under the poverty line is eligible. Under Obamacare, you could enroll in private insurance exchanges only if your income exceeded the poverty line.

The tax credit system employed in the Senate Republican bill is stronger than the A.C.A.’s, because it adjusts the value of the credits not only to benefit those with low incomes but also to encourage younger people to enroll in coverage.
