A U.S. Republican Senator on Sunday predicted that the Obamacare repeal bill would fail due to rising sign that the new bill has problems. 'My opinion is that it’s likely to be dead,' said senator john mccain, senior U.S. Republican, as part of the CBS program "Face the Nation."

A proposal from the Senate, which faces a united Democratic opposition, was further threatened during a week when several Republican Senators had to return to their states and face their constituencies who are firmly against the bill. Senators return to Washington on Monday.

Republican health care overhaul bill

The Senate Bill keeps a large part of Obamacare intact but has a large part of its funding removed. It repeals most of affordable care act (Obamacare) taxes, revises tax cuts under the law, and terminates the expansion of Medicaid. It also exceeds Obamacare's abolition by revoking Medicaid funding from 2025.

White House chief of staff Reince Priebus said on Sunday that U.S. President Donald Trump expects Congress to adopt a bill to abolish and replace the Affordable Care Act

Republican Senator Ted Cruise said on Sunday that failure to comply with the bill 'is not an option" and said that the Senate's efforts should aim at reducing insurance premiums. He pointed to the amendment he proposed, as assessed by the Congressional Budget Office, which assesses the impact of the bill.

Cruz’s changes will allow insurance companies to offer plans that do not meet Obamacare's mandate to impose people the same prices and cover a range of basic health benefits, such as maternity and medical treatment, prescriptions, and plans that meet Regulations.

Cruz's plan attracted support from conservative senators and groups claiming that the change will help reduce premiums.

But moderate Republicans and external critics say that it will weaken the protection of people with existing conditions and make their insurance unaffordable.

Slim chances for passage at the Senate

Senate Majority Leader Mitch McConnell intends to hold a vote on legislation that needs support for at least 50 out of 52 Republicans in the Senate before a six-week vacation that starts July 29.

Even McConnell questioned the prospect of the bill skating through last week. McConnell said that if the Congress does not fulfill a seven-year commitment to abolish Obamacare, it must act to maintain the markets of private health insurance companies and provide a way to find a bipartisan solution to the health system.
