The poll, conducted June 28, was consistent with Gallup polling earlier in the year, which showed roughly equal percentages of Americans calling congressional passage of the act a good thing vs. a bad thing, Gallup officials said.
Asked what they want Congress to do now that the Supreme Court has upheld the 2010 law, 31 percent of U.S. adults said they would repeal the law entirely and 21 percent said they would keep the law in place, but repeal parts of it.
Twenty-five percent of U.S. adults Americans said they would like Congress to pass legislation to expand the government's role in healthcare beyond what the current law does, while 13 percent said they want to keep the law in place and do nothing further.
Sixty-five percent of Democrats said they wanted to maintain if not expand, the law, while 85 percent of Republicans want the Affordable Care Act repealed in whole or in part. Independents were more evenly divided, with 40 percent in favor of keeping or expanding the law and 49 percent in favor of repealing all or part of the law.
The telephone poll of 1,012 U.S. adults -- part of the Gallup Daily tracking survey -- has a margin of error of 4 percentage points.
