House Republican leaders are working intensively to gather votes for the American Health Care Act, a sweeping bill that would overhaul the health care system, effectively repealing and replacing Obamacare. An earlier attempt at passage in March failed, but the bill has been amended, and a new vote is planned for Thursday.

Will the bill pass the House?

Estimates vary about precisely where the vote count stands. Several news organizations, including The New York Times, are performing an unofficial “whip count,” repeatedly asking members of Congress how they plan to vote and why. The numbers above represent the aggregated answers reported by five news outlets, including The Times.

Below, the Republican lawmakers each organization is counting as a “no” vote.

The differences among published counts reflect the fluidity and uncertainty of the situation, as well as varying levels of strictness about what constitutes a “no” vote. Democrats have said they will unite against the bill, so Speaker Paul Ryan can afford only 22 defections by Republicans*.

Negotiations are expected to continue. Republican lawmakers have already made several revisions to the bill, many devised to appeal to the party’s right flank, and some meant to lure votes from members of the New York delegation. Additional changes to win votes remain possible.
