Republicans' Obamacare repeal bill fails in US Senate

In a stinging blow to President Donald Trump, U.S. Senate Republicans failed on July 28 to dismantle Obamacare, falling short on a major campaign promise and perhaps ending a seven-year quest by their party to gut the healthcare law.

Voting in the early hours, three Republican senators, John McCain, Susan Collins and Lisa Murkowski, crossed party lines to join Democrats in a dramatic 49-to-51 vote to reject a "skinny repeal" bill that would have killed some parts of Obamacare.

"This is clearly a disappointing moment," Senate Republican leader Mitch McConnell said on an eerily quiet Senate floor right after the vote. 

"The American people are going to regret that we couldn't find a better way forward."

The setback leaves Trump without a major legislative win after more than six months in power, despite Republicans controlling the White House, Senate and House. It will also be a let-down for financial markets, which expected Trump to make rapid changes to healthcare, taxes and infrastructure spending.

"3 Republicans and 48 Democrats let the American people down. As I said from the beginning, let Obamacare implode, then deal. Watch!" Trump tweeted after the vote.

Trump has repeatedly berated congressional Republicans for being unable to overcome internal divisions to repeal Obamacare, but has offered no legislation himself, nor any clear guidance on what he would like to do about replacing the law.

The president has demanded at various times that Obamacare should be allowed to collapse on its own, that it should be repealed without replacement, and that it should be repealed and replaced.
