Trump 'unlikely' to face primary challenger, says pollster

"Consistently, six out of 10 to seven out of 10 Republicans pick Trump over any of the other names," Nesho told Hill.TV's Joe Concha, referring to those, including outgoing Ohio Gov.

"So it's very, very unlikely that he will face a primary challenger, and even though independents and Democrats might have slightly different preferences, that doesn't matter," he continued. "It's ultimately registered Republicans that will decide that question." 

"I think Trump is safe heading into 2020, and frankly, it's his party," he said. 

Trump still enjoys widespread popularity among Republican voters nearly two years into his tenure in office. 

Gallup found last week in its weekly tracking poll on the president's approval rating that 90 percent of Republicans approve of Trump's performance in office.
