Price suggested Friday that the federal contribution should be dropped to 90 percent immediately. While the issue is not currently under "official" consideration in the budget conference committee, he said, many House Republicans are discussing such a proposal.
"Many states didn't expand," Price told National Journal Daily. "So all citizens are subsidizing the states that expanded. So the fair thing to do, from my perspective and many individuals' perspective, is to have the same, at least the same "¦ 10 percent match by the states."
Such a move would pull the rug out from those governors who have already agreed to the expansion, and it would have an outsize effect on Democrats. Seventeen of the 25 states that have expanded are controlled by Democratic governors, including in Rhode Island, where Gov. Lincoln Chafee recently changed his party affiliation from independent.
The Obama administration has bent over backwards to reassure states that they can count on full federal funding. The administration went so far as to change its position and oppose Medicaid cuts it had proposed — a move explicitly designed to send a signal to states that were worried about the federal commitment to Medicaid funding.
The GOP proposal to renege on the commitment isn't new. Republicans have been saying for months that the full federal funding was unlikely to come through, while the concern about the government's commitment to its promise was a key argument in many states' decisions not to accept the expansion.
Asked whether Republicans had set themselves up for a self-fulfilling prophecy, given their earlier warnings that states shouldn't rely on the federal funding, Price said: "We're $17 trillion in debt. At some point you've got to get fiscally responsible."
The proposal is another in a series of Republican efforts to undermine aspects of President Obama's health care law.
"Republicans trying to scare people across the country with lies about the Medicaid expansion would be a bit more credible if they didn't come back to D.C. and fight to shift the costs onto states and families themselves," one Senate Democratic aide said Friday.
Democrats on the budget conference committee strongly oppose Price's idea, saying the issue is a nonstarter. "That's not going anywhere," said House Budget Committee ranking member Chris Van Hollen, D-Md., on Friday.
"Rather than try and reduce the amount [the federal government is giving], those states that are not allowing people to participate should allow them. Right now, they're denying 5 million Americans affordable health care. Five million people. And they somehow want to be rewarded for that," Van Hollen added.
Asked whether he thought he could get significant numbers of Democrats on board with the idea, Price shook his head. "Oh, probably not.... Their ability to embrace positive solutions is limited," he said, laughing.
But the discussion alone could convince some of the states still considering an expansion to back away from the idea. "I think they join at their own peril. There's no guarantee that that money's going to be there," Price said.
"What I'm trying to do is what's fair and appropriately represent my constituents, yeah," he said.
