Approval of ObamaCare has not improved since President Obama announced more than 8 million people had signed up for insurance through the healthcare exchanges.
According to an Associated Press-Gfk online poll, 43 percent of people continue to disapprove of the law, while 28 percent support it.
Twenty-eight percent of people neither support nor oppose the law.
The results are unchanged since the firm tested the question in late March, weeks before the deadline for open enrollment that brought a surge of new signups through the exchanges. In fact, disapproval has not seen any significant change going back to December.
In a small sample of those who said they signed up or had a family member sign up, 40 percent said the premiums are about what they expected. Thirty-two percent said they are lower than expected, while 27 percent said they are higher than expected.
Republicans have used the issue of increased premiums as a cudgel to attack the healthcare law ahead of the midterm elections.
A majority, 51 percent, of those who said they had successfully signed up for the law said they approve of it. Approval drops to 30 percent among those who were unsuccessful.
More than a third of people who either tried or had a family member try to sign up said they were unsuccessful in doing so.
The poll surveyed 1,354 people online and has a margin of error of plus or minus 3 percent.
