A pollster has argued that the Democrats are losing the backing of working class voters because they are perceived to support undocumented immigrants.
Stanley Greenberg, who worked as a pollster for former President Bill Clinton, based his conclusions on focus groups and polls he conducted, according to the Washington Examiner.
"The Democrats have moved from seeking to manage and champion the nation's growing immigrant diversity to seeming to champion immigrant rights over American citizens,'" Greenberg explained, according to the Examiner.
Greenberg stated that more than 60 percent of respondents believe granting legal status to undocumented immigrants would "lead to greater competition for public services and more than half believe it would take jobs from American citizens."
He added that half believe legalizing undocumented immigrants would result in a "drain on government services."
Greenberg suggested that such sentiments were not confined to white workers, but encompassed all races.
"The Democrats don't have a white working-class problem. They have a working-class problem," he added.
Some Democrats take a similar position to Greenberg. Independent Sen. Bernie Sanders of Vermont, who challenged Hillary Clinton in the Democratic presidential primary in 2016, called in his immigration policy for tougher border controls.
"Should we have a completely open border so that anyone can come in the United States of America? If that were to happen, which I strongly disagree with, there is no question in my mind that that would substantially lower wages in this country," Sanders said in 2015, according to Real Clear Politics.
Greenberg's conclusions are challenged by other polling data. A Quinnipiac University poll published in February found that 51 percent of Americans opposed President Donald Trump's travel ban against immigrants from seven Muslim-majority countries.
Findings from the survey, conducted Feb. 2-6, revealed that 60 percent of respondents rejected the halting of all refugee programs, and 70 percent opposed an indefinite ban on Syrian refugees.
A CNN/ORC poll released in March found that 60 percent of Americans wanted to see a legal pathway created for illegal immigrants to be able to stay in the country rather then see them deported. 90 percent said they would support granting citizenship to illegal immigrants who speak English, have a job and pay taxes.
The poll, carried out March 1-4, also showed that 58 percent of respondents feared efforts to deport immigrants would go too far, compared to 40 percent who worried they would not go far enough, CNN reported.
