WASHINGTON (AP) — Voters in Mississippi’s Democratic primary ranked health care as the most important issue facing the country, well above climate change, the economy, race relations, foreign policy and many other social issues.

About 4 in 10 named health care, an issue that has intensely divided the field of Democratic candidates. Roughly 2 in 10 had the economy on their minds, according to a wide-ranging AP VoteCast survey of the Democratic primary electorate in Mississippi.

The Associated Press declared Joe Biden the winner just after the polls closed Tuesday in Mississippi. He was boosted in particular by strong support from African Americans.

Here’s a snapshot of Democratic voters in Mississippi — who they are and how they voted — based on preliminary results from AP VoteCast, a survey of 1,091 voters, conducted for The Associated Press by NORC at the University of Chicago.

DO THEY WANT A BIG CHANGE ?

Voters in Mississippi’s Democratic primary were more likely to support a candidate who would restore the political system to how it was before Donald Trump was elected in 2016 than one who would bring fundamental change to Washington.

WHAT ELSE VOTERS WANT

About 9 in 10 said it was very important that a nominee can beat Trump, and about as many said it was highly important that the candidate cares about people like them and displays strong leadership.

Roughly 8 in 10 said a nominee should have “the right experience” and the best policy ideas.

Being willing to work across the aisle was considered very significant for a Democratic nominee by about 7 in 10 voters.

SUPPORT BY RACE

Among white voters in Mississippi, Biden had an advantage over Bernie Sanders.

That lead widened among black voters. Nearly 9 in 10 black voters supported the former vice president over the Vermont senator.

SUPPORT BY AGE

Biden led among voters across age groups, though he enjoyed a wider advantage among voters ages 45 and older compared with younger voters.

LARGELY UNIFIED AGAINST TRUMP

A wide majority say they will definitely vote for the Democratic candidate against Trump in the general election. Still, about 2 in 10 say their decision will depend on which Democrat is on the ballot in November.

PRIMARY PROCESS SKEPTICISM

Voters in Mississippi were rather confident that the Democratic Party’s nomination process is fair. About half the voters say they are very confident that the process for selecting a presidential nominee is fair, and roughly 4 in 10 said they are somewhat confident. Just about 1 in 10 have little to no confidence.

DEBATING HEALTH CARE

The campaign has featured a contentious debate among candidates over the best way to tackle health care, an issue seen as the most important facing the country by about 4 in 10 voters.

There is majority support for a government-run health care system for all Americans, with about two-thirds of voters saying they are in favor. Roughly a third are opposed.

But support for a public option, where every American could buy into a government-run insurance plan if they wanted to, is even higher. Roughly 9 in 10 are in favor.

About 6 in 10 voters are in favor of either proposal, while roughly a quarter say they favor a public option but oppose a single-payer system.

THE ECONOMY, CLIMATE CHANGE AND OTHER ISSUES

Roughly 2 in 10 voters said the economy is the most important issue facing the nation. A significant majority described the economic system in this country as unfair. That includes about 4 in 10 voters who said it’s very unfair.

About another 1 in 10 voters called climate change the top issue. About 6 in 10 voters expressed support for a tax on the use of carbon-based fuels, such as coal, oil and natural gas.

Roughly 1 in 10 named race relations as most important. Small shares of voters considered immigration, foreign policy or abortion most important.
