With uncertainty about jobs, the economy and life, many young people want certainty about health insurance. A new poll by the Kaiser Family Foundation found that seven out of ten 18-to-30-year-olds say health insurance is “very important.”

Almost half of those under 65 polled say they or someone in their home has a pre-existing condition.  And 25 percent say that they or a family member, at some point, was denied insurance because of the condition.

Obamacare, or the Affordable Care Act (ACA) will prohibit insurance companies from denying coverage to people on the basis of health status or pre-existing medical conditions beginning in 2014.  But this poll found that many still don’t like the idea of Obamacare because they think the law “goes too far in changing the healthcare system.”

Interestingly, what the healthcare law is called is important. Forty-two percent say they have a favorable opinion of Obamacare compared to 35 percent for “the health reform law.” On the other hand, 47 percent have a negative view of Obamacare.
