WASHINGTON, D.C. -- Sen. John McCain announced Friday in a statement that he cannot "in good conscience" vote for the GOP's latest plan to overhaul Obamacare, likely ending Republicans' latest effort to repeal and replace the Affordable Care Act.
"I cannot in good conscience vote for the Graham-Cassidy proposal," the Arizona Republican said in a statement. "I believe we could do better working together, Republicans and Democrats, and have not yet really tried. Nor could I support it without knowing how much it will cost, how it will (affect) insurance premiums, and how many people will be helped or hurt by it. Without a full CBO score, which won't be available by the end of the month, we won't have reliable answers to any of those questions."
McCain's "no" vote makes it very likely Republicans won't be able to repeal and replace Obamacare before September 30, as Sen. Rand Paul of Kentucky said he would not back the effort and Sen. Susan Collins of Maine is also expected to vote "no" on the proposal.
Republicans need at least 50 votes to pass the measure under the process of reconciliation.
McCain was one of three most-watched members on the fence and considered a key vote on the bill. Without his support, Republicans would need to get Sen. Lisa Murkowski, a Republican from Alaska, as well as Collins to sign on. It's unlikely considering the fact that Collins said Friday afternoon that she was leaning against the bill and had key concerns that the legislation did not do enough to protect individuals with pre-existing conditions.
"I'm leaning against the bill," Collins said Friday at a Portland, Maine, event, according to The Portland Press Herald.
McCain's announcement comes despite that one of the bill's key sponsors -- Sen. Lindsey Graham of South Carolina -- is a close confidant. The thinking was if anyone could convince McCain to vote "yes," it would be Graham.
"I take no pleasure in announcing my opposition. Far from it," McCain said. "The bill's authors are my dear friends, and I think the world of them. I know they are acting consistently with their beliefs and sense of what is best for the country. So am I."
McCain has said for weeks that he would not support health care legislation that had not gone through "regular order," meaning Senate hearings, an amendment process and a rigorous floor debate.
McCain voted "no" on the last health care proposal in July for the same reason. McCain's dramatic floor vote, which happened just weeks after he was diagnosed with brain cancer, came in the early morning and was captured as one of his most "maverick" moments in the Senate.
