An internal GOP poll from the party's Senate campaign arm shows former Kansas Secretary of State Kris Kobach with a commanding lead over the Republican primary field unless Secretary of State Mike Pompeo Michael (Mike) Richard PompeoWatchdog confirms State Dept. canceled award for journalist who criticized Trump Trump's push for win with Sudan amps up pressure on Congress Putin nominated for Nobel Peace Prize MORE were to enter the fray.

The Wall Street Journal reports that the poll, conducted for the National Republican Senatorial Committee, found Kobach with the support of 43 percent of likely Kansas primary voters if Pompeo is not in the mix.

However, with Pompeo hypothetically on the GOP primary ballot, the secretary of State garnered 54 percent of GOP support compared to Kobach’s 17 percent.

"Mike would win easily in Kansas," Trump said. "He came to me and said 'Look, I'd rather stay where I am,' but he loves Kansas, he loves the people of Kansas. If he thought there was a chance of losing that seat, I think he would do that and he would win in a landslide."

Sixty percent of likely voters who support Kobach would shift support to Pompeo should he enter the race, the poll found. In a head-to-head matchup, Pompeo would beat Kobach 68 percent to 24 percent, the survey found, according to the Journal.

While Kobach leads in the poll without Pompeo in the race, Republicans are wary of his chances of winning the general election after he lost his 2018 gubernatorial bid to Democrat Laura Kelly.

"If Mike Pompeo doesn't run, we don't have a prayer," a Republican strategist who had seen the poll told The Wall Street Journal.

A previous poll reported on by the Journal found Kobach losing to a Democrat in the 2020 Kansas Senate race by 10 percentage points.

Kobach touted the polling numbers showing him with strong support should Pompeo remain on the outside.

"These numbers reflect what we have seen on the campaign trail. Republicans across Kansas overwhelmingly support our campaign," Kobach told the news outlet. "And there is still room to grow and push the needle past 50 percent."

The poll was conducted by phone from Oct. 21-23 and surveyed 607 likely Kansas primary voters. The poll's margin of error is plus or minus 4.1 percentage points.
