SIMI VALLEY, California – Republican presidential frontrunner Donald Trump stepped into a hornet&39;s nest in Wednesday&39;s debate as rivals turned their sights on the billionaire, while Carly Fiorina showed she had earned her place on the main stage.
Ten challengers flanked Trump on stage at the Ronald Reagan Presidential Library in California, seeking an opening against the man who has defied all political odds to lead the race for the party&39;s nomination ahead of the November 2016 election.
"Mr Trump, we don&39;t need an apprentice in the White House, we have one right now," Wisconsin Governor Scott Walker told Trump – a snarky reference to the title of the real estate mogul&39;s reality television show.
Trump swiftly returned fire, living up to his billing as the campaign bulldog by attacking his rivals, further imposing himself on the race to determine who will battle the Democratic nominee, likely Hillary Clinton, for the White House.
"In Wisconsin I went to number one, and you went down the tubes," Trump retorted, highlighting Walker&39;s slumping poll numbers.
The remarks near the top of the marathon three-hour debate kicked off several minutes of Trump-related thrusts and parries that have so far defined much of the 2016 presidential race.
Many, like early presumptive frontrunner Jeb Bush, were under intense pressure to deliver a breakout performance – or risk a campaign meltdown that could see them shunted aside as the first state nomination votes in February draw nearer.
Fiorina, the sole woman in the Republican race and the only candidate to rise from last month&39;s "undercard" debate to Wednesday&39;s main stage, delivered by many accounts a command performance.
The former chief executive of Hewlett-Packard offered passionate calls for defunding women&39;s health care provider Planned Parenthood, a publicly funded organisation that offers abortions.
She also delivered a withering response to Trump&39;s insulting comments about her looks that he made in a recent magazine interview.
"I think women all over this country heard very clearly what Mr Trump said," she said, offering him a cold stare and earning loud applause.
Trump, in a rare concession, replied: "I think she&39;s got a beautiful face, and I think she&39;s a beautiful woman."
But Fiorina was not done.
She dominated the middle portion of the debate, showing command of military figures, slamming Clinton for what she called a lack of accomplishments, delivering an emotional call for increased drug treatment as she recalled losing a child to addiction and hitting Trump over his business practises.
"You ran up mountains of debt, as well as losses, using other people&39;s money," Fiorina said.
"Why should we trust you to manage the finances of this nation?"
Earlier, a foursome of low-polling candidates took their shots at Trump in the "undercard" debate.
A fiery Senator Lindsey Graham warned against nominating "cartoon character" Trump, while former New York governor George Pataki declared Trump "unfit to be president of the United States".
The main event&39;s 11 candidates clashed extensively on issues including immigration, how to handle a looming government shutdown, and dealing with Russian President Vladimir Putin.
Bush, perhaps the campaign&39;s ultimate establishment Republican, has seen his political fortunes tumble in the months since Trump entered the race, and he sought to claw back some of his lost ground by projecting himself as an even-keeled conservative who can lead from day one.
The former Florida governor tangled with Trump over speaking Spanish in the US, and provided a witty retort to Trump&39;s accusation that he is a "low-energy" candidate.
Asked what he would want his Secret Service handle to be if he were elected, Bush said "Ever-ready. It&39;s very high-energy, Donald".
But Bush was forced into an awkward defence of his brother George W Bush, who was president on September 11, 2001 and launched divisive wars in Afghanistan and Iraq after the terror attacks on American soil.
"There is one thing I know for sure – he kept us safe," Bush said.
"I don&39;t know, do you feel safe right now?" Trump replied. "I don&39;t feel so safe."
As more conventional candidates like Ohio Governor John Kasich and Senator Marco Rubio struggle to gain precious air-time with the media, another outsider, retired neurosurgeon Ben Carson has quietly gained ground and now sits second in the polls.
While it is unclear whether Carson poses an immediate threat to Trump&39;s dominance, the rise of the doctor – who like Trump has never held public office – is more evidence of an anti-establishment wave washing over the nomination race.
"When I entered this race, all the political pundits said it was impossible," Carson said. "We now have over 500,000 donations and the money is coming in."
Here are some notable moments in the highly personal joust:
Money, money, money
"I say not in a braggadocious way, I&39;ve made billions and billions of dollars dealing with people all over the world."
Donald Trump lays on his characteristic bombast from the outset.
"She&39;s absolutely the love of my life, and right here, and why don&39;t you apologise to her right now."
Former Florida governor Jeb Bush demands an apology from Trump for the suggestion he is soft on immigration because he has a Mexican-American wife, who was in the audience.
School yard fights
"His visceral response to attack people on their appearance, short, tall, fat, ugly, my goodness, that happened in junior high. Are we not way above that?"
Senator Rand Paul takes issue with Trump&39;s personal insults on the campaign trail.
"I never attacked him on looks, and believe me, there is plenty of subject matter there."
Trump shows gives no quarter in response.
"I think women all over this country heard very clearly what Mr Trump said."
Former Hewlett-Packard CEO Carly Fiorina addresses Trump&39;s comments about her face.
"A fully formed foetus on the table, its heart beating, its legs kicking while someone says we have to keep it alive to harvest its brain. This is about the character of our nation."
Fiorina gets rapt applause for an impassioned attack on Planned Parenthood – government-funded reproductive health clinics that have become a lightning rod for conservatives because they also provide abortions.
"I&39;m (as) entertained as anyone by this personal back and forth about the history of Donald and Carly&39;s career, for the 55-year-old construction worker who doesn&39;t have a job, who doesn&39;t have money to fund his child&39;s education, I gotta tell you the truth. They could care less about your careers. They care about theirs."
New Jersey Governor Chris Christie is unimpressed by a back-and-forth between the campaign&39;s two CEOs on their business record.
Does your Mom know, Jeb?
"Forty years ago I smoked marijuana... I&39;m sure other people did it and didn&39;t want to admit it in front of 40-million people... My mom’s not happy that I just did."
Bush comes clean on his pot use.
"I, too, have travelled hundreds of thousands of miles around the globe but unlike Mrs Clinton, I know flying is an activity, not an accomplishment."
Fiorina offers a curt dismissal of Clinton&39;s frequent travel as secretary of state.
Each candidate was asked what they would choose as their Secret Service code name. Christie opted for "True Heart", John Kasich for "Unit Two" (his wife was unit one), secretary-turned-CEO Fiorina went with "Secretariat", Scott Walker chose "I love riding Harleys".
Bush tried a drop of self-deprecation with "Ever ready", joking at Trump&39;s criticisms about the tempo of his campaign. "Very high energy, Donald", he quipped.
The real estate mogul opted for "Humble", raising laughs, Ben Carson ("One Nation"), Cruz ("Cohiba"), Floridian Marco Rubio ("Gator"), Mike Huckabee ("Duck Hunter"), Paul ("Justice never sleeps") – which the moderator noted was a mouthful.
