Pollster Mike Greenfield told Hill.TV on Wednesday that it is unlikely President TrumpDonald John TrumpJimmy Carter: 'I hope there's an age limit' on presidency White House fires DHS general counsel: report Trump to cap California trip with visit to the border 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) HaleyJuan Williams: Why does Trump fear GOP voters? Can Carl DeMaio save the California GOP? Treasury: US deficit tops trillion in 11 months 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.
