More than half of Americans are concerned about voter fraud in the November election, according to a PR/PBS News/Marist poll released Thursday. 

Fifty-eight percent of Americans say they are either very concerned or concerned that voter fraud will occur and 42 percent are not very concerned or not concerned at all that ineligible voters will vote or cast a ballot more than once.

GOP members who took the survey were avid about their concerns about voter ethics. Eighty-six percent of Republicans and 55 percent of independents said they are concerned about voter fraud compared to 33 percent of Democrats. 

Republicans were also concerned that people who are not citizens would cast a ballot, with 81 percent of their responses casting doubt on the process followed by 53 percent of independents and 25 percent of Democrats.

Non-citizen voters have become a top concern for the party as former President Trump continues to bash Vice President Harris’s approach to spur the country's influx of migrants. 

“For nearly four years, we have been living through the worst border crisis in the history of the world,” Trump said during a last-minute scheduled appearance at Trump Tower in New York on Thursday.

However, data shows voting by non-citizens is rare.  

Despite that, 52 percent of Americans are either concerned or very concerned that people who are not U.S. citizens will be allowed to vote this year. Forty-eight percent are not very concerned or not concerned at all that this will occur, and less than one percent are unsure. 

Another other top concern among survey takers was international election interference. 

About two in three Americans or 66 percent say they are either very concerned or concerned that foreign countries will interfere with this year’s elections, 34 percent are not very concerned or not concerned at all that this will occur, and less than one percent were unsure. 

Sixty-nine percent of Americans say they are very confident or confident in the United States Postal Service's ability to deliver election-related mail to voters and election officials in a timely way this year.

Thirty percent are not very confident or confident that election materials will be delivered expeditiously.

The survey was conducted through live interviewers, by text, or online from Sept. 27th to Oct. 1 with adults age 18 or older. There were 1,628 participants whose responses were within the margin of error at plus or minus 3.3 percentage points.

Results for registered voters were within the margin of error at plus or minus 3.5 percentage points and results for likely voters were within plus or minus 3.7 percentage points.
