But support for a public option, where every American could buy into a government-run insurance plan if they wanted to, is even higher. About 9 in 10 are in favor.
About 6 in 10 voters are in favor of either proposal, while about 3 in 10 say they favor a public option but oppose a single-payer system.
CLIMATE CHANGE, THE ECONOMY AND OTHER ISSUES
Roughly 3 in 10 voters said climate change is the most important issue facing the nation. A wide majority — about 8 in 10 — expressed support for a tax on the use of carbon-based fuels, such as coal, oil and natural gas.
Just about 1 in 10 called the economy the top issue. But a significant majority described the economic system in this country as unfair. That includes about 4 in 10 who said it’s very unfair.
Small shares of voters considered race relations, immigration, gun policy or abortion most important.
AP VoteCast is a survey of the American electorate conducted by NORC at the University of Chicago for The Associated Press and Fox News. The survey of 1,186 voters in Minnesota was conducted for seven days, concluding as polls closed. Interviews were conducted in English or Spanish. The survey is based on interviews with a random sample of registered voters drawn from the state voter file. The margin of sampling error for voters is estimated to be plus or minus 5.3 percentage points.
