With the White House still well short of the 215 votes it needs to get the deeply unpopular American Health Care Act through to the Senate—where it is dead on arrival anyway—Republican leadership officially cancelled Thursday’s planned House vote.

Despite Donald Trump’s professed negotiating prowess, the president and his senior leadership team failed to reach a deal with the House Freedom Caucus after meeting Thursday to discuss the legislation. “Nothing new was agreed upon,” Rep. Paul Gosar of Arizona, told The Hill as he left the White House. Rep. Jeff Duncan echoed the sentiment. “He was very gracious, he laid out his points but no firm decision has been made by those in the room,” the South Carolina congressman said.

From the outset, hard-line House conservatives have criticized the A.H.C.A., which they argue doesn’t do enough to roll back Obamacare. Earlier this week, leadership tried to sway the dissenters by adding a handful of sweeteners, including provisions designed to crack down on Medicaid beneficiaries (among the changes were new rules imposing work requirements), but caucus members still balked. On Wednesday night, White House budget director Mick Mulvaney went further, reportedly meeting with Rep. Mark Meadows, the chairman of the Freedom House Caucus, to discuss gutting the Affordable Care Act’s requirement that all health-care plans provide a number of “essential health benefits.” But slashing emergency services, mental health, and maternity benefits apparently did little to appease the Ayn Rand fan club. As of this afternoon, Meadows declared there is still “no deal” on the A.H.C.A., whose tax credits conservatives argue are too generous.

Within hours of Meadows’s declaration, Speaker of the House Paul Ryan indefinitely postponed a press-conference to discuss the bill, and Republican leadership and the Trump administration confirmed that the fate of the health-care plan in the House would not be decided on schedule.

The timing of the re-scheduled vote had not been announced as of Thursday afternoon. A White House aide told CNN that it would likely take place Friday morning, while Senate Majority Leader Mitch McConnell reportedly informed senators that the vote might not occur until Monday. In the meantime, House Republicans will hold a closed door meeting at 7 p.m. on Thursday to discuss how the party can salvage the controversial measure, which is bleeding support on multiple fronts.

In its attempt to win over conservatives by moving the health-care legislation further to the right, the White House has all but guaranteed its failure in the Senate. To pass the bill in the upper house of Congress, G.O.P. leadership can only lose two Republican votes, assuming that Vice President Mike Pence will vote yes in the event of a tie and all Democrats will vote no. More than a half-dozen moderate Senate Republicans have already balked at the anemic tax credits under the G.O.P. plan and raised concerns about the estimated 24 million Americans likely to lose or drop coverage over the next ten years—largely driven by the plan’s deep cuts to Medicaid, which is wildly popular even in states Trump won.

Even if the A.H.C.A. does manage to squeak through the House, allowing the bill to die in the Senate might be a mercy. A new Quinnipiac poll released Thursday found that 46 percent of Americans would be less likely to support their elected representatives if they vote “yes.” The political calculus looks even worse if the G.O.P. managed, against all odds, to be signed into law. Just 17 percent of respondents approve of the bill now; just wait until they see what’s actually in it.
