According to the poll, 69 percent of young Americans between the ages of 15 and 34 favor a national health plan, known as a single-payer program. Eighty-eight percent of young Democrats and 40 percent of young Republicans favor a government-run health insurance program, according to the poll. Roughly two-thirds of young independents are in favor.

Young Americans called health care a very important issue in deciding how to vote. Sixty-two percent of those who will be old enough to vote in the midterms rated it as such. That’s the most who said the same of any issue in the poll, including immigration and the economy.

Thirty-three-year-old Jasmine Miller, of Detroit, said that she pays $800 a month for health insurance to cover herself and her son. Miller, who describes herself as a humanitarian, said that health care is among the issues she cares about most.
