ORLANDO, Fla. (AP) - Straying from his trademark bravado, Donald Trump acknowledged Thursday his presidential campaign is facing challenges and could ultimately fall short - a rare expression of humility by the Republican presidential nominee.
Trump's most explicit concession came as he pleaded for support at a gathering of evangelical ministers, where Trump observed he was "having a tremendous problem in Utah." The same day, the billionaire celebrity acknowledged his lack of political correctness could cost him the election if Americans reject his blunt approach.
"We're having a problem," Trump told the ministers, adding the next president could get to nominate up to five high court justices. "It could cost us the Supreme Court."
After trouncing 16 challengers in the Republican primary, Trump is encountering worrying signs as his campaign moves into the general election. Democrat Hillary Clinton's lead over Trump in national polls has widened in recent days, while a number of fellow Republicans have declared they won't support their own party's presidential nominee.
Trump's exercise in self-awareness was a marked departure from his usual tenor on the campaign trail, where for months at rallies he would tick through poll numbers showing him winning as if they were sports scores of his favorite team.
"We're going to win so big," Trump told a roaring crowd one month ago at the Republican National Convention.
Yet on Thursday, Trump was reduced to citing a poll that actually showed him a few points behind Clinton and arguing the race between them was close. Asked by CNBC how he planned to reverse the advantage Clinton has opened over him, Trump said he simply planned to do "the same thing I'm doing right now."
"At the end, it's either going to work, or I'm going to, you know, I'm going to have a very, very nice, long vacation," Trump said.
In Utah, typically a reliably Republican state, Trump's challenges have been particularly striking. The state's large Mormon population has voiced serious skepticism about Trump, though the state's GOP governor has endorsed him.
"We've really been given a false narrative," Trump said of his struggles in Utah.
Yet in other traditionally GOP-leaning states like Arizona and Georgia, too, Republicans are concerned Trump's unpopularity could give Democrats an improbable victory. The concerns are compelling enough that dozens of worried Republicans gathered signatures Thursday for a letter to the GOP party chairman urging him to stop helping Trump and focus on protecting vulnerable House and Senate candidates.
Expressing anything other than confidence this close to Election Day is unusual for a presidential nominee. But GOP strategist Mike DuHaime, who advised Trump ally Chris Christie's presidential bid, said there could be benefits to Trump's newfound self-awareness.
"Showing some vulnerability, admitting there are some vulnerabilities, humanizes him and could potentially make him more likable," DuHaime said.
At the evangelical summit in Orlando, Trump beseeched religious leaders to convince their followers to show up to vote for him, gently chiding evangelicals for failing to vote in large enough numbers for GOP nominee Mitt Romney in 2012. He said Christians, who make up a majority of the American electorate, need to have their voices heard.
"Whatever you can do, I appreciate it," he said.
Trump's unusually candid reflection about the uncertainty of his electoral prospects came as he's struggled to keep the focus on his opponent - Clinton - and avoid unwanted distractions. Earlier this week, he caused a major stir with comments about the Second Amendment that were perceived as advocating violence against Clinton and found himself facing questions yet again after declaring Wednesday President Barack Obama was the "founder" of the Islamic State group - a claim that's patently false.
