The majority of Republican voters said they would support postponing the 2020 election at President Trump's request to ensure only eligible Americans can vote, according to a new poll.

The new survey from Ariel Malka, associate professor of psychology at Yeshiva University, and Yphtach Lelkes, assistant professor at the Annenberg School for Communication at the University of Pennsylvania, found 52 percent of Republicans would back postponement of the 2020 election if Trump requested the contest be delayed.

Fifty-six percent said they would delay the 2020 election if both the president and congressional Republicans requested a postponement.

The poll's authors said they asked Republican respondents a series of questions related to Trump's statements on voter fraud, including whether they believe Trump won the popular vote, whether millions of illegal immigrants voted, and how often they believe voter fraud occurs.

Republican voters were then asked two questions about delaying the 2020 election: Whether they would back postponement if Trump said the election should be delayed to ensure only eligible American citizens can vote, and whether they would back postponement if Trump and Republicans in Congress said it should be delayed to ensure only eligible American citizens can vote.

According to the poll, 47 percent of Republican voters think Trump won the popular vote, and 68 percent believe millions of illegal immigrants voted. Seventy-three percent believe voter fraud occurs somewhat or very often.

The study's authors concede they were measuring responses to a hypothetical situation, and noted any suggestion to postpone the 2020 election would be met with opposition across the political spectrum.

But Malka and Lelkes said they don't believe their findings can be dismissed.

"At a minimum, they show that a substantial number of Republicans are amenable to violations of democratic norms that are more flagrant than what is technically proposed (or studied)," they wrote in the Washington Post. "And although the ensuing chaos could turn more Republicans against this kind of proposal, it is also conceivable that a high-stakes and polarized debate would do the exact opposite."

Though Trump lost the popular vote to Hillary Clinton by more than 2.8 million votes, he often says the result would've been different had 3 to 5 million illegal immigrants not voted for Clinton in the 2016 election. There has been no proof offered to support this claim.

Earlier this year, the president launched the Presidential Advisory Commission on Election Integrity to study voter fraud.

Lelkes and Malka interview 1,325 Americans from June 5-20, and focused specifically on 650 respondents who said they identified with or leaned toward the GOP.
