A Hill.TV American Barometer survey of 1,001 registered voters conducted Nov. 16-17 found that Trump would easily defeat onetime presidential rival, Ohio Gov. John Kasich. Among self-identified Republican respondents, 67 percent said they would choose Trump while only 14 percent said they would back the outgoing Ohio governor.

In a hypothetical two-way matchup, of those surveyed, just 9 percent of Republican voters supported Flake while 70 percent backed Trump in the poll.

Among independent voters (who are allowed to vote in party primaries in many states, including the first in New Hampshire), Kasich presents a more stiff challenge to Trump.

Of those that identified as independents, 33 percent said they would support Kasich while 28 percent said they would back Trump. Trump remained ahead among all voters with 33 percent support to the outgoing Ohio governor's 32 percent.

While Kasich's potential bid might have some currency among independents, ultimately, it is Republican voters who will determine Trump's future within the party, said Dritan Nesho, CEO of HarrisX, the company that conducted the survey.

"Even though independents and Democrats might have slightly different preferences, that doesn't matter. Ultimately it's registered Republicans that will decide that question," Nesho said during Tuesday's broadcast of "What America's Thinking."

"Frankly, it's his party," Nesho said. "By a factor of two-to-one, almost half of Republicans associate with Trump over the party."

No current or former Republican officials have announced a primary challenge to the president, but several remaining anti-Trump politicians have urged others to make a go of it.

During a Sunday interview with CNN, Flake said that he would be unlikely to mount a challenge to Trump.

“I think the future of the party is with people with an optimistic vision moving ahead. I don’t think that will be me. I think there are better candidates out there. But somebody needs to run,” he told host Jake Tapper.

Flake will be departing from the Senate at the end of the year. He declined to run for reelection after several polls of Arizonans found that his anti-Trump image made him unpopular among Republicans. In July, a Morning Consult survey found that Flake was the second-least popular senator in his or her own state. 

In the latest American Barometer survey, Flake was the second-least popular potential GOP challenger among Republican respondents. Nebraska Sen.
