Washington (CNN) - Do Americans support or oppose the health care law?
As the clock ticks towards a federal government shutdown over Republican attempts to weaken or eliminate the Affordable Care Act, that question is front and center in the standoff.
Democrats and Republicans say they have public opinion on their side when it comes to the measure - also known as Obamacare - and a new CNN national poll seems to give both sides some ammunition.
According to a CNN/ORC International survey released Monday morning, 57% of Americans say they oppose the law, up three percentage points from a CNN survey in May, with 38% saying they favor the measure, down five points from May.
That's the number Republicans will highlight.
"It is time for the Senate to listen to the American people just as the House has listened to the American people and to pass a one year delay of Obamacare and a permanent repeal of the medical device tax," said House Speaker John Boehner Monday morning.
But it's not the whole story.
Supporters of the law will point to a second number in the survey: 39% of all Americans oppose the health care law because it's too liberal, with 11% of the public saying they oppose the measure because it isn't liberal enough. Add that 11% to the 38% who say they favor the law and that means that about half the public supports the law or don't think it goes far enough.
"It's sometimes difficult to remember, but at the start of the health care debate in 2009, many Democrats wanted nothing less than a single-payer system and were extremely disappointed when that approach was not part of the new law. That disappointment seems to have persisted among some groups," says CNN Polling Director Keating Holland.
CNN/ORC has been asking the "support/oppose" question and the "too liberal/not liberal enough" breakdown since March 2010, before the bill was passed by a then Democrat controlled Congress and signed into law by Obama.
The poll was conducted for CNN by ORC International September 27-29, with 803 adults nationwide questioned by telephone. The survey's overall sampling error is plus or minus 3.5 percentage points.
