CNN Poll: Is Obamacare working?

Washington (CNN) - More than half the public says Obamacare has helped either their families or others across the country, although less than one in five Americans say they have personally benefited from the health care law, according to a new national poll.

A CNN/ORC International survey also indicates that a majority of Americans oppose the Affordable Care Act, but that some of that opposition is from people who don't think the measure goes far enough.

The poll, conducted this past weekend, was released on Wednesday, one day after a federal appeals court upheld Obamacare tax subsidies. That ruling came just a couple of hours after a separate appeals court struck down such subsidies for the millions of Americans enrolled in the federal government's HealthCare.gov exchange.

According to the poll, only 18% of the public say they or their families are better off now that the major provisions of the health care law have been implemented. Another 35% report that, while their lives have not improved, the Affordable Care Act has benefited other people in the U.S. Add those two numbers together, and that means 53% say that Obamacare has helped either their families or others across the country.

Forty-four percent tell us that the health care law has not helped anyone in the country.

According to the poll, 40% of Americans say they support the health care law, basically unchanged from March but up from 35% in December, which was a record low in CNN polling. Fifty-nine percent of those questioned say they oppose the measure, down five points from December.

"Not all of the opposition to the health care law comes from the right," said CNN Polling Director Keating Holland. "Thirty-eight percent say they oppose the law because it's too liberal, but 17% say they oppose it because it's not liberal enough. That means more than half the public either favors Obamacare, or opposes it because it doesn't go far enough."

As expected, the poll indicates a continued wide partisan divide between Democrats and Republicans over the law and whether it’s working.

Political battle over Obamacare

The measure was passed into law in 2010, when the Democrats controlled both houses of Congress. The law, considered President Barack Obama's signature domestic achievement, was a major issue in 2010 and 2012, and is again in 2014, as many Republicans continue to call for Obamacare to be repealed and replaced.

While the Obamacare website suffered a disastrous rollout last autumn, things have improved. Major flaws with HealthCare.gov were addressed and major gains in enrollment were made.

But Republicans continue to keep their midterm campaign focus on the health care law. Earlier this month House Speaker John Boehner made Obamacare the focus of his lawsuit against the President.

The GOP obsession with the health care law may be smart politics: Midterm electorates are smaller than those of presidential elections, and the contests are often all about getting out base voters–and the GOP base continues to hate Obamacare.

The poll was conducted for CNN by ORC International from July 18-20, with 1,012 adult Americans questioned by telephone. The survey's overall sampling error is plus or minus three percentage points.
