Three in 10 U.S. adults who say they’re likely to vote in November’s presidential election are very or moderately worried about being able to afford their health insurance and out-of-pocket costs for prescription drugs over the next year, according to a new poll from NBC News and the Commonwealth Fund. Nearly 80 percent, meanwhile, believe that reducing health care costs should be a high priority for the next president. 

The nationally representative poll, the first in a series tracking attitudes of likely voters on top health care issues this election season, also finds that Democrats and likely voters who are leaning Democratic are the most worried about health care costs, along with people with incomes under $50,000, blacks, and Hispanics. And three in 10 young adults 18 to 34 — a group some consider to be pivotal to the election’s outcome — said a health problem of theirs or a family member worsened because they delayed getting care or taking needed medication because of the cost.
