The anti-establishment wave that swept President TrumpDonald John TrumpTrump: WHCA picking non-comedian for headliner a 'good first step' Five takeaways from Mississippi's Senate debate Watergate’s John Dean: Nixon would tell Trump 'he's going too far' MORE into power in 2016 is still very much in play for the 2018 midterms, pollster Mallory Newall said on Monday.

"What you're seeing is this new era of anti-establishment politics that we started to see, obviously in 2016, with the rise of Donald Trump himself," Newall, research director at Ipsos Public Affairs, said on Hill.TV's "What America's Thinking."

"It's still very much in play here," she added. "You see that with seasoned Democrats losing their primaries to more liberal up-and-comers as well."

While Trump was seen as the first major anti-establishment figure to grip U.S. politics with his White House victory two years ago, the left has seen a slew of anti-establishment candidates gain popularity this election cycle.

Similarly, former NAACP President Ben Jealous is an anti-establishment Democrat locked in a gubernatorial battle with Maryland Gov. Larry Hogan (R).

Democratic strategist Basil Smikle told The Hill in June that the wave of anti-establishment candidates is about the party's push for new ideas.

“There’s a huge appetite for a candidate that pushes big, aspirational ideas and not someone preoccupied with shaping public policy within the constraints of their office,” Smikle said.
