WASHINGTON — Republican senators struggled to gather more support for a last-ditch attempt to repeal Obamacare on Monday despite revising funding provisions of their bill to make it more attractive to a handful of undecided lawmakers.

The outcome remained in doubt with several senators in the party voicing concerns in recent days about the legislation to dismantle Democratic former President Barack Obama’s signature healthcare law.

An economic assessment by Standard & Poor’s Global Ratings threw more cold water on the bill. If enacted, it would result in 580,000 lost jobs and $240 billion in lost economic activity by 2027, keeping GDP growth “stuck in low gear of around 2 per cent at best.”

In hopes of finding more backing, Republican senators leading the effort released a changed version of their bill that included a table showing some states where senators have been undecided, such as Alaska and Maine, would get more money.

For seven years, Republicans have hammered Obamacare, which extended health insurance to some 20 million Americans, as an unwarranted and costly government intrusion into healthcare, while also opposing taxes it imposed on the wealthy.

President Donald Trump made repealing Obamacare one of his top campaign promises in 2016. Democrats have fiercely defended it.

A Senate Finance Committee hearing on the healthcare legislation on Monday was disrupted by protesters chanting “No cuts for Medicaid, save our liberty.”

Capitol Hill police removed the protesters, many in wheelchairs, from the hearing room.

A total of three Republican defections would kill off the latest anti-Obamacare effort. Republican Senators John McCain, Rand Paul and Ted Cruz have said in recent days they would voteno. Other senators such as Susan Collins and Lisa Murkowski have also voiced reservations.

A spokesman for Paul said on Monday the senator still opposes the latest version despite the tweaks. A Cruz aide said the Texas conservative “is not currently a ‘yes’ on this bill, but we continue to work towards lowering premiums.”

Slim Margin

Trump said there was little room for Republican wavering on healthcare.

“We have 52 senators, so you lose two, you’re out,” he told the Alabama-based "Rick and Bubba" radio program on Monday.

“We don’t have much a margin. We don’t have any margin.”

Democratic leaders roundly rejected the revised draft of the repeal legislation as a sleight of hand to gain support.

Once the protests on Capitol Hill had died down, Teresa Miller, acting secretary for the Pennsylvania Department of Human Services, told the Senate hearing that states would not be able to sustain the deep cuts projected under the latest healthcare legislation.

I’ve been thinking a lot over the past few days about what we would do in Pennsylvania if this bill passes and becomes law,” she said. “And honestly, I struggle to figure out how we would respond. We would have two years to completely revamp our healthcare system.

The last attempt to repeal Obamacare fell one vote short in July, in a humiliating setback for Trump and Senate Majority Leader Mitch McConnell.

The new bill, originally introduced by Senators Lindsey Graham and Bill Cassidy, would take federal money spent on the Medicaid programme for the poor and disabled, as well as subsidies to help Americans buy private insurance, and divvy it up to the states in block grants. Advocates say that would give states more discretion to manage their own healthcare schemes.

Opponents fear undoing Obamacare will mean millions lose healthcare, including some with pre-existing medical conditions.

The two largest health insurer lobbying groups on Monday renewed their criticism of the bill, sending testimony to the

Senate that it would destabilise the individual health insurance market and hurt consumers.

US hospital stocks were down across the board on Monday morning, in broadly bearish trading marketwide. Shares of HCA Healthcare Inc and Tenet Healthcare Corp were hit particularly hard, falling 2.8 per cent and 5 per cent, respectively, in afternoon trading. — AFP
