Sen. John McCain announced he would not vote in favor of the newest attempt to repeal the Affordable Care Act, the latest Republican to throw the last-ditch effort in jeopardy.

  • Sen. John McCain voting no on Graham-Cassidy
  • Sen. Rand Paul also a no vote; Sen. Susan Collins leaning toward "no"
  • If at least 3 Republicans and all Democrats vote no, the bill fails

McCain announced that he could not "in good conscience vote for Graham-Cassidy," which would repeal significant parts of the ACA. 

McCain also said he could not support it without knowing how the bill would affect Americans. Senate Republican leaders are trying to push the bill through without getting an analysis by the non-partisan Congressional Budget Office.

Democrats are unanimously opposed to the bill. Sen. Rand Paul, R-Kentucky, announced he was against the bill because it did not repeal enough of the ACA's taxes. 

Sen. Susan Collins, R-Maine, said she was also leaning against the bill. Collins voted against the last effort to repeal the ACA because it would have dramatically affected Medicaid. 

Analysts says the Graham-Cassidy bill would result in billions of federal dollars moved from states that expanded Medicaid under ACA to states that did not. Funds would be turned into block grants for the states in 2020, and then disappear completely in 2027. 

There is also some concern as to how the bill would affect those with pre-existing conditions. Republicans pushing Graham-Cassidy say the bill would give states greater control and flexibility over health care, including how pre-existing conditions and essential benefits are covered. But they insist nothing will change.

Democrats and most health industry groups say that leaving the issue to the states does not guarantee people with pre-existing conditions will be able to find insurance, or let alone affordable insurance, especially since the market will be less regulated. 

Republicans control the Senate with a 52-48 majority. With three senators leaning towards a no vote, the Graham-Cassidy bill is currently not expected to survive the Senate.
