More than four years after the Affordable Care Act was enacted, six in ten (60 percent) Americans say the healthcare reform law has not had a direct impact on them or their family, a survey by the Henry J. Kaiser Family Foundation finds.

According to the Kaiser Health Tracking Poll: May 2014, 14 percent of all respondents said the law had helped them, 24 percent said it had hurt them, and 60 percent said it had no direct impact on them. Predictably, the responses varied by political affiliation, with Democrats more likely to say the ACA had helped (26 percent) than hurt (8 percent) them, and Republicans more likely to say it had hurt (37 percent) than helped (5 percent) them. The most commonly cited negative impact of the legislation known as Obamacare was an increase in healthcare costs (14 percent), while the most commonly cited positive impact was a family member obtaining or keeping coverage (5 percent of the public overall).

The survey also found that the public's perception of the ACA remained unchanged a month after the close of the open enrollment period, with 38 percent of Americans holding a "very" or "somewhat" favorable view of the law and 45 percent holding a "very" or "somewhat" unfavorable view. Republicans were nearly twice as likely to express a "very" unfavorable view (61 percent) as Democrats were to have a "very" favorable one (36 percent).

In addition, the poll surveyed registered voters' views in advance of congressional midterm elections and found that 51 percent of all respondents (69 percent of Democrats and 35 percent of Republicans) said they are tired of hearing candidates talk about the law and want them to focus more on other issues such as jobs, while 43 percent (26 percent of Democrats and 60 percent of Republicans) said it is important for candidates to continue to debate Obamacare.
