Pollster Dalia Mogahed said in an interview on "What America's Thinking" that aired Thursday that voter suppression tactics are rooted in a fear of changing demographics in the U.S.

"A lot of this is about a fear of a changing America," Mogahed, director of research at the Institute of Social Policy and Understanding (ISPU), told Hill.TV's Jamal Simmons on Wednesday.

"Demographic changes in America have really invigorated some pockets of our country, and I think the Trump win is a symptom of that, and voter suppression is another symptom of that," she continued.

A new American Barometer poll, conducted by Hill.TV and the HarrisX polling company found that Americans were split over whether voter suppression or voter fraud was a bigger issue.

Fifty-one percent of respondents said voter suppression was a bigger issue, while 49 percent said the same about voter fraud.

The issue of voter fraud has taken center stage in Georgia's gubernatorial race after a report found that state officials removed an estimated 107,000 people from voter rolls because they decided not to vote in prior elections.

"Purging roles, saying that if you didn't vote the last election you're not allowed to vote this election, it is targeting a specific type of American," Mogahed said. "It's targeting people of color, poor people, young people, and it's trying to exclude. It's trying to disenfranchise a group of Americans that some Americans don't want to be a part of this country."
