Left-leaning voters say it’s more important to take back the White House in 2020 than to nominate a Democratic candidate who represents their values, according to a new poll from the PBS NewsHour, NPR and Marist.

Among voters likely to back a Democrat, 54 percent said they want a Democratic candidate who can beat President Donald Trump in the 2020 presidential election. In contrast, 42 percent of respondents said they want Democrats to pick a nominee whose values most reflect their own.

“Democrats want to beat Trump. That’s the goal, and they’re looking for the best candidate to do that.”

On July 30 and 31, 20 eligible Democratic presidential candidates will enter the next series of debates, a chance for them to give voters a better glimpse of what kinds of policies they’d prioritize as president. The poll did not ask people which Democratic presidential candidate they preferred, and voters still have plenty of time to decide which primary candidate to support. Most Democrats and Democratic-leaning independents — 82 percent — said they haven’t made up their minds yet, compared to 17 percent of left-leaning voters said they know who they want to see run for president.

“Democrats want to beat Trump. That’s the goal, and they’re looking for the best candidate to do that,” Democratic strategic Doug Thornell said. “They haven’t made up their minds. They’re window-shopping right now.”

Looking at a bigger pool of registered voters nationwide, just more than half said they definitely do not plan to vote for Trump in 2020. That includes 54 percent of people who consider themselves politically independent, 92 percent of Democrats, and 7 percent of Republicans. Another 39 percent of registered voters said they plan to cast their vote for Trump.

Trump’s job approval has inched up to its highest spot in Marist polling since he took office. Nationwide, 44 percent of U.S. adults said they approve of the president’s performance. Since February 2017, Trump’s job approval has hovered between 35 percent and 43 percent.

The results signal that independent voters in particular aren’t sold on any of the 2020 Democratic presidential hopefuls or Trump, said Lee Miringoff, the director of the Marist Institute for Public Opinion.

By comparison, voters were split on President Barack Obama in August 2011, the summer leading up to his re-election, according to Marist polling. Forty percent of registered voters said they planned to vote for him, another 40 percent said they would not, and the remaining 20 percent of voters said they were unsure.

This latest Marist poll also asked voters about key issues at the center of the presidential race.

The vast majority of U.S. adults — 89 percent — said they think background checks for gun purchases are a good idea. In February, 82 percent of U.S. adults said background checks would help reduce gun violence, according to a PBS NewsHour/NPR/Marist poll.

When it comes to health care, 70 percent of Americans said they support the Medicare for All proposals floated by some 2020 Democrats, so long as people can choose between a national health insurance program or their own private health insurance. That includes broad support from 90 percent of Democrats, 70 percent of independents and 46 percent of Republicans.

Only 41 percent of Americans said they wanted to replace private health insurance with a government-run program.

And 67 percent of U.S. adults — including a majority of Republicans, Democrats and independents — said the government should regulate prescription drug prices. Fewer than half of U.S. adults, 44 percent, said they want to repeal the Affordable Care Act, also called Obamacare.

Additionally, 64 percent of Americans said they support a pathway to citizenship for immigrants who are in the U.S. illegally. Twenty-seven percent of Americans support decriminalizing border crossings, and a third said they back offering a national health insurance program to immigrants who are in the U.S. illegally.

Other proposals from 2020 White House hopefuls were less popular. Democratic presidential candidate Andrew Yang has proposed setting up a universal basic income of $1,000 per month for each U.S. adult — but that appeals to just 26 percent of Americans. That includes 42 percent of Democrats and 8 percent of Republicans.

Just 27 percent of Americans overall support paying reparations to the descendents of slaves, though the support was split along party lines; 46 percent of Democrats support reparations, compared to 23 percent of independents and 3 percent of Republicans.

Democrats “need to reorient their rhetoric to the voters they need, not the voters they already have.”

Republican strategist Mike Murphy argued Democratic presidential contenders were “running right for the tricky stuff,” like supporting reparations and decriminalizing the border, that could backfire in a general election.

Republicans “can’t believe their good luck,” Murphy said. Democrats are: “racing to put themselves so far into the corner on these issues that even Trump might be able to beat them.”

Democrats will secure progressive voters, Murphy said, but they “need to reorient their rhetoric to the voters they need, not the voters they already have.”

The PBS NewsHour, NPR and Marist conducted a survey July 15-17 that polled 1,346 U.S. adults with a margin of error within 3.5 percentage points, including 1,175 registered voters with a margin of error of 3.7 percentage points and 553 Democrats and Democratic leaning independents with a margin of error of 5.4 percentage points.
