Presidential front-runner Donald Trump currently holds 48 percent support among registered Republicans, a new NBC/Survey Monkey Weekly Election Tracking poll showed.
Republican presidential candidate Sen. Ted Cruz of Texas falls 20 points behind Trump, with 27 percent support among registered Republicans. Republican Gov. John Kasich of Ohio took 18 percent of the support — two points higher than the previous poll.
The poll also showed that 57 percent of registered Republican and Republican-leaning voters said that Trump should be the nominee if he wins a plurality of delegates, despite many in the GOP establishment floating the idea of a new candidate entering the race in time for the convention if Trump doesn't win the 1,237 delegates needed.
"If we don't have a nominee who can win on the first ballot, I'm for none of the above. They all had a chance to win. None of them won. So I'm for none of the above," House Speaker John Boehner said after Marco Rubio suspended his campaign.
Trump has continued to lead the GOP field despite continued controversial comments and rhetoric — most recently defending his past comments about women.
"If Megyn Kelly were a man, I’d be saying the exact same thing of Megyn Kelly. I don’t think there should be a double standard if someone’s a woman," he said on a conservative radio show of his insults towards the Fox News anchor, Fortune reported.
"I’ve been better to women than any of these candidates."
Though Trump has gained support for his outspokenness and often divisive language, even some of his closest supporters have begun to turn the other way. Ann Coulter voiced disappointment with Trump in an interview with Breitbart's Milo Yiannopoulos.
"I just wish it would be a [teensy] bit less lowbrow," she said following a now-infamous Twitter battle between the billionaire and rival Cruz. "It’s like constantly having to bail out your 16-year-old son from prison.”
Coulter also referred to Trump as "mental" in the interview, and said she's "a little testy" with him following recent behavior, says Salon.
