Pollster says Trump unlikely to face 'significant' primary challenge

Pollster Mike Greenfield told Hill.TV on Wednesday that it is unlikely President TrumpDonald John TrumpTrump says 'Failing New York Times' should be held 'fully accountable' over Russia report Trump says 'Failing New York Times' should be held 'fully accountable' over Russia report Trump tweets ICE will begin removing 'millions' of undocumented migrants MORE will face a significant Republican primary challenger in 2020.

"I think it's very unlikely that anybody is going to challenge Trump in a significant way," Greenfield told host Jamal Simmons on "What America's Thinking."

Greenfield referred to a Change Research poll conducted in February, which found most hypothetical Republican challengers trailing the president in early primary state South Carolina. 

"Most of the candidates are well under 10 percent against Trump," he said. "Even Nikki HaleyNimrata (Nikki) HaleyOvernight Defense: US to send 1K more troops to Mideast amid Iran tensions | Iran threatens to break limit on uranium production in 10 days | US accuses Iran of 'nuclear blackmail' | Details on key defense bill amendments Overnight Defense: US to send 1K more troops to Mideast amid Iran tensions | Iran threatens to break limit on uranium production in 10 days | US accuses Iran of 'nuclear blackmail' | Details on key defense bill amendments UN nominee Kelly Craft to face confirmation hearing Wednesday MORE, who's from South Carolina — really has everything going for her — polls in the low 20s against Trump."

Haley, the former U.S. ambassador to the United Nations, came in far ahead of the other Republicans polled, getting 21 percent of the vote in a hypothetical match-up with Trump.

Former Massachusetts Gov. William Weld (R), who on Monday became the first to officially launch a primary challenge against Trump, came in with just 3 percent of the vote. 

Former Ohio Gov. John Kasich (R) came in with 3 percent of the vote as well. He said on Wednesday that all of his options were on the table for 2020.
