More Americans now disapprove of the legislation, and many expect their costs to rise and the quality of their care to worsen; few expect the reforms to help them.
President Obama has continued to tour the country to stump for his new set of reforms. This week he went to Portland, Maine, where he told people it will take more than a week for the benefits of reform to become apparent.
The poll, conducted March 29 through April 1, found that so far the president's efforts to build up support for the bill appear to be ineffective.
Fifty-three percent of Americans say they disapprove of the new reforms, including 39 percent who say they disapprove strongly. In the days before the bill passed the House, 37 percent said they approved and 48 percent disapproved.
