Socialist isn’t a taboo word, at least among Iowans eying the 2020 Democratic caucuses.

More than half of likely 2020 Democratic caucusgoers say they would be satisfied with a presidential candidate who wants the U.S. to be more socialist.

Fifteen percent would be “very satisfied” with such a candidate and 41 percent would be “mostly satisfied.” Thirty-three percent would be dissatisfied, and 11 percent are not sure, according to the new Des Moines Register/CNN/Mediacom Iowa Poll of likely Democratic caucusgoers.

That’s roughly comparable to a 2016 Iowa Poll in which 43 percent of likely Democratic caucusgoers said they identify as “socialist.” That was more than the 38 percent who identified as “capitalist.”

Socialism became a rallying cry in the Democratic presidential race after Sen. Bernie Sanders, who self-identifies as a Democratic socialist, joined the 2016 race to take on Hillary Clinton. Sanders, of Vermont, is an independent, not a Democrat, in the Senate — although he caucuses with Democrats — but in both 2016 and this year, he is running for president as a Democrat.

Sanders has claimed his influence — and popularity — has caused other Democratic candidates to approach this part of their economic policy differently.

Whether a candidate embraces socialism or capitalism in their economic policies has been a more important issue this election than in previous years.

Former Gov. John Hickenlooper, a Democratic presidential candidate, shied away from calling himself a capitalist in an interview on MSNBC’s “Morning Joe” program Friday.

“I think most Democrats don't care as much about the labels,” he said in the interview.

Although many candidates still identify as capitalist, not going quite as far as Sanders, many say that there are problems with capitalism in its current form while on the campaign trail. Progressives like Massachusetts Sen. Elizabeth Warren told Bloomberg TV, "capitalism without rules is theft.”

“I believe in capitalism. I see the wealth that can be produced, but let’s be really clear," Warren said, "encouraging companies to build their business models on cheating people — that’s not capitalism.”

In an interview over the weekend, Warren also made clear she is neither a Democratic socialist or a centrist.

Former Rep. John Delaney, who has been running for president since 2017, says he is for a "more just form of capitalism," not socialism.

Even if some candidates don’t identify as socialist, many still embrace policies further left than previous years — many candidates support the "Green New Deal" proposed by first-time Rep. Alexandria Ocasio-Cortez, a member of the Democratic Socialists of America, and have called for Medicare-for-all in some form, which Sanders championed in 2016.

Those issues find support among likely Democratic caucusgoers.

Eighty-one percent say they hope candidates will spend “a lot” of time talking about health care, and 84 percent say they prefer a candidate who supports shifting to a government-run health care system of Medicare-for-all, either all at once or incrementally. Forty-nine percent of respondents say they prefer a candidate who supports Medicare-for-all “in full,” and 35 percent who endorses it “in steps.”

Eighty percent of poll respondents say candidates should spend “a lot” of time talking about climate change. Ninety-one percent say they prefer a candidate who supports the "Green New Deal," which couples government programs to address climate change with support for jobs in the clean energy sector to help address poverty. That includes 65 percent who favor a candidate who supports the "Green New Deal" in full and 26 percent who favor approaching it in part.
