Thirty-five percent of respondents in one nationwide poll did not know that the Affordable Care Act is the same thing as Obamacare, or thought that they were entirely distinct policies.

According to a Morning Consult poll, the results of which were published by the New York Times on Tuesday, 17 percent of respondents incorrectly believed that Obamacare and the ACA were different policies. Eighteen percent said they didn’t know whether they were the same or different.

The Times reported the poll found misunderstandings to be more prevalent among two groups of people who could be greatly affected by ACA repeal: those aged 18 to 29 and those who earned less than $50,000.

Meanwhile, 72 percent of Republicans understood the two terms referred to the same health care policy, according to the survey.

Morning Consult conducted its poll from Jan. 25-26 using online surveys of a national sample of 1,890 adults. The data was weighted to approximate a target sample of adults based on age, race/ethnicity, gender, educational attainment and region. The margin of error is 2 percentage points.
