John McCain is pursued by reporters after casting a 'no' vote on a a measure to repeal parts of Obamacare.

"We should not make the mistakes of the past." Rumours swirled late Thursday the Arizona Republican, who had captured the nation's sympathy this week after delaying his cancer treatment in order to return to Washington, might vote against the GOP's "skinny repeal" plan – a watered-down version of earlier Republican proposals to repeal the 2010 healthcare law. McCain warned at a hastily arranged news conference Thursday afternoon that he was leaning against supporting the legislation unless House Speaker Paul Ryan, assured GOP senators that the House would not move to quickly approve the bill in its current form. McCain and Senator Lindsey Graham and Ron Johnson wanted Ryan to launch broad House-Senate negotiations for a wider rollback of the law. Two hours later, Ryan issued a statement signalling he would launch negotiations, and Graham and Johnson announced their support.

But few, if any, of his Republican colleagues realised what was about to transpire. Two votes were called just after midnight. The first was on a Democratic proposal to refer the "skinny repeal" bill back to a committee. The second vote was to pass "skinny repeal," which would have repealed the Affordable Care Act's individual mandate and rolled back a tax on medical devices. Republican Senator Susan Collins.

McCain stood on the Republican side of the room nodding in agreement.

Vice-President Mike Pence was already at the Capital prepared to break a tie. Instead, he launched a last-ditch effort to win McCain's support. As the first vote began, McCain took his seat next to Graham, his closest friend in the Senate. The South Carolinian mostly nodded as McCain gesticulated, and signalled – through his body language – that he was likely to vote no. When Murkowski walked over to join the conversation, McCain winked and gave her a thumbs down – signalling his intentions.

GOP Senator Jeff Flake, who operates in McCain's long shadow, stood next to Senate Majority Leader Mitch McConnell, Senator John Cornyn, who counts GOP votes, and Pence. Eventually, Flake was dispatched to talk to McCain.

He obliged, walked over to McCain and asked Graham to move over one seat. But McCain did not acknowledge Flake, focusing instead on Murkowski and Collins.

Seeing that Flake was not making progress, Pence walked over at 12:44am. McCain smiled, pointed at Collins and Murkowski, said something about "marching orders," and stood up.

"Mr Vice President," he said, greeting Pence. For the next 21 minutes, the Vice-President cajoled McCain, Collins and Murkowski. Twice during the conversation, a Pence aide came to whisper in Pence's ear – other reporters learned it was the White House calling. Pence finally left to take a call, but later returned to speak with McCain. By then, other senators around the room realised what was happening. "You could see the body language in the entire chamber change in two hours," Senator David Perdue recalled. "One side was kind of ebullient, moving around and talking and the other side was subdued, and all of a sudden it began to change. There was an instinctive reaction that maybe this thing wasn't going to pass. Nobody knew for sure." "It was pretty sombre," added Senator Amy Klobuchar. At 1.10am, McCain crossed the Senate Chamber to talk to Schumer, Klobuchar and other Democrats. As he approached, McCain told them he worried that reporters watching from the gallery above could read his lips. When he realised that the press was indeed watching, he looked up at the ceiling and shouted, "No!" as senators and reporters laughed. Then, Democrats beamed when McCain shared his news.

The vote on "skinny repeal" began at 1:24am, but McCain was out in the lobby once again conferring with Pence. In his absence, Collins and Murkowski cast their "no" votes along with the 48 members of the Democratic caucus. McCain returned at 1:29am without Pence, approached the Senate clerk and gave a thumbs down - the third "no" vote. Several people gasped. Others applauded. Reporters dashed out to report the news. McCain returned to his seat, walking past Cornyn and Republican senators John Thune and Bill Cassidy, who stood grim-faced and despondent. Cassidy rubbed his face several times with his hands. Thune's face contorted. The colour in Cornyn's face seemed to drain. "Certainly Senator McCain knows how to improve the drama," Cassidy recalled later.

The vote concluded, and the results were announced – 49 to 51. Just days before, McCain had fired a warning shot with a lengthy floor speech that criticised the rushed, secretive process that led to "skinny repeal." Early Friday morning, McCain, Collins and Murkowski delivered the fatal blow. McConnell, humiliated by the results, stood to address his colleagues. The colour of his face now matched the pink in his necktie. Loading "This is clearly a disappointing moment," he said. Washington Post
