Americans favor ObamaCare to the Graham-Cassidy health-care legislation by more than 20 points, according to a new ABC News/Washington Post poll.

Fifty-six percent of Americans surveyed said they preferred the current health-care law to the latest repeal-and-replace legislation put forth by Senate Republicans, while only 33 percent of those polled said they supported the new legislation. 

The latest poll shows that public sentiment has not necessarily changed since Republican efforts to repeal ObamaCare in July.

Fifty percent of Americans polled preferred ObamaCare, while just 24 percent of those polled approved of the “skinny” bill repeal efforts in July.

The Graham-Cassidy legislation would repeal parts of ObamaCare, including an expansion of Medicaid that comes with new federal funding. It would then send block grants to states, which state governments could use to deliver health-care services.

The poll comes after the Graham-Cassidy bill suffered a critical blow on Friday when Sen. John McCain (R-Ariz.) announced he would not vote for the legislation, opting instead to hope for a bipartisan solution. 

“I cannot in good conscience vote for the Graham-Cassidy proposal. I believe we could do better working together, Republicans and Democrats, and have not yet really tried,” McCain said in a statement. 

McCain’s defection and Sen. Rand Paul’s (R-Ky.) earlier declaration that he would vote “no” forces Senate Republican leadership to attempt to win over every other Republican in the conference. 

McCain was one of three GOP senators to kill the GOP efforts in the Senate to pass an ObamaCare repeal bill in July. The other two Republicans to vote “no” on that legislation, Alaska’s Lisa Murkowski and Maine’s Susan Collins, have not said how they intend to vote on the Graham-Cassidy measure. 

The ABC News/Washington Poll was conducted Sept. 18-21 among 1,002 adults. The survey has a sampling error of 3.5 percentage points.
