"It is always astounding to me how well he's still able to project this message of being the common man's guy," Mogahed, director of research at the Institute of Social Policy and Understanding (ISPU), told Hill.TV's Jamal Simmons.

"Despite his own background, despite his actual policies that favor the rich, and yet, we still find that among his base, he's believed," she continued. "They trust him to fight for them."

A recent Hill-HarrisX survey found that Trump's approval rating stood at 62 percent among rural voters polled, while 53 percent of white voters said they approved of the president's job in office.

Trump was able to win over rural and white voters in 2016 in states that have tended to vote Democratic in recent years, such as Michigan and Wisconsin.

Trump and Republicans in recent weeks have accused Democrats of being "socialists" attempting to overhaul the U.S. economic system, a line of attack some centrists fear could resonate with undecided voters in 2020.

Democratic presidential hopefuls, meanwhile, have seized on anti-corporate policy proposals as they look to win the support of top labor unions and frame themselves as working-class advocates.
