He is a reclusive hedge fund billionaire who made a fortune using complicated algorithms to bet on things other people could not see.
One of his gambles was on US President Donald Trump.
His backing of the long-shot presidential candidate has made Robert “Bob” Mercer, the former co-chief executive of Renaissance Technologies, the top powerbroker in Republican politics today.
The Mercer family is not nearly as well-known as the industrialist Koch brothers or the Las Vegas casino magnate Sheldon Adelson when it comes to supporting right-wing causes in the US, and they are more than happy to keep it that way.
Mercer, 71, who worked as a computer scientist at IBM before joining Long Island-based Renaissance Technologies, has always shunned the limelight.
According to numerous accounts, Mercer is socially awkward and intensely private.
He is described in Michael Wolff’s bombshell new book Fire and Fury: Inside the Trump White House as “almost nonverbal, looking at you with a dead stare and either not talking or offering only minimal response.”
Robert Mercer in November abruptly announced that he was stepping down as co-chief executive of Renaissance Technologies because of the unwanted press scrutiny brought about by his political activities.
In his resignation letter, Mercer also made his most expansive public comments to date, outlining the core principles of his libertarian philosophy.
“I believe that individuals are happiest and most fulfilled when they form their own opinions, assume responsibility for their own actions and spend the fruits of their own labor as they see fit,” he said. “This is why I support conservatives, who favor a smaller, less powerful government.”
In his book about the Trump White House, Wolff expanded further on what he said was the Mercer family doctrine.
He said they were attempting to build a “radical free-market, small-government, home-schooling, anti-liberal, gold-standard, pro-death penalty, anti-Muslim, pro-Christian, monetarist, anti-civil-rights political movement in the United States.”
With the silver-haired Mercer patriarch remaining behind the scenes, it is up to Rebekah, 44, the second of his three daughters, to channel the family money to conservative causes and maintain the direct line to the White House.
While the Koch brothers and other Republican mega-donors sat out the 2016 presidential race because of a distaste for Trump, the Mercers threw their considerable resources behind the brash real-estate tycoon after initially backing Texas Senator Ted Cruz.
They donated millions to Trump’s coffers and persuaded his then-floundering campaign to take on board two figures seen as instrumental to his upset victory over former US secretary of state Hillary Rodham Clinton — anti-establishment ideologue Steve Bannon and pollster Kellyanne Conway.
Robert Mercer, who reportedly has an abiding hatred of the Clintons, is a long-time patron of Bannon, who headed the right-wing Web site Breitbart News until becoming chief executive of Trump’s election campaign.
When Trump angrily severed ties with Bannon over comments he made in Wolff’s book, it was a damaging blow to his former White House chief strategist.
However, the coup de grace to Bannon’s any remaining political ambitions might have had came a few days later, when the Mercer family pulled the plug on their long-time ally.
“I support President Trump and the platform upon which he was elected,” Rebekah Mercer said in a rare public statement. “My family and I have not communicated with Steve Bannon in many months and have provided no financial support to his political agenda, nor do we support his recent actions and statements.”
The excommunication marked the end of the long-standing collaboration between the Mercer family and Bannon, who had been a fringe player in Republican politics until a US$10 million investment by the Mercers turned Breitbart News into a powerful conservative voice.
The Mercers are estimated to have contributed a total of more than US$100 million to conservative causes over the past decade, including funding for the Government Accountability Institute.
Rebekah Mercer serves as chairwoman of the board of the Florida-based institute cofounded by Bannon, whose stated mission is to root out “cronyism and corruption.”
The institute is perhaps best known for a 2015 book by its president, Peter Schweizer, that was highly critical of the Clintons: Clinton Cash: The Untold Story of How and Why Foreign Governments and Businesses Helped Make Bill and Hillary Rich.
Besides contributing to Breitbart and the institute, the Mercers also invested in Cambridge Analytica, a political data analysis firm whose efforts have been credited with helping Trump win the 2016 election.
While Bannon has for years been the Mercers’ frontman for their political activities, his departure from the scene would not appear to lessen their influence.
According to the Daily Beast, before repudiating Bannon, Rebekah Mercer held a telephone call with the White House, where she spoke with Trump.
The US Senate’s passage of the 2026 National Defense Authorization Act (NDAA), which urges Taiwan’s inclusion in the Rim of the Pacific (RIMPAC) exercise and allocates US$1 billion in military aid, marks yet another milestone in Washington’s growing support for Taipei. On paper, it reflects the steadiness of US commitment, but beneath this show of solidarity lies contradiction. While the US Congress builds a stable, bipartisan architecture of deterrence, US President Donald Trump repeatedly undercuts it through erratic decisions and transactional diplomacy. This dissonance not only weakens the US’ credibility abroad — it also fractures public trust within Taiwan. For decades,
In 1976, the Gang of Four was ousted. The Gang of Four was a leftist political group comprising Chinese Communist Party (CCP) members: Jiang Qing (江青), its leading figure and Mao Zedong’s (毛澤東) last wife; Zhang Chunqiao (張春橋); Yao Wenyuan (姚文元); and Wang Hongwen (王洪文). The four wielded supreme power during the Cultural Revolution (1966-1976), but when Mao died, they were overthrown and charged with crimes against China in what was in essence a political coup of the right against the left. The same type of thing might be happening again as the CCP has expelled nine top generals. Rather than a
Taiwan Retrocession Day is observed on Oct. 25 every year. The Democratic Progressive Party (DPP) government removed it from the list of annual holidays immediately following the first successful transition of power in 2000, but the Chinese Nationalist Party (KMT)-led opposition reinstated it this year. For ideological reasons, it has been something of a political football in the democratic era. This year, the Chinese Communist Party (CCP) designated yesterday as “Commemoration Day of Taiwan’s Restoration,” turning the event into a conceptual staging post for its “restoration” to the People’s Republic of China (PRC). The Mainland Affairs Council on Friday criticized
The topic of increased intergenerational conflict has been making headlines in the past few months, showcasing a problem that would only grow as Taiwan approaches “super-aged society” status. A striking example of that tension erupted on the Taipei MRT late last month, when an apparently able-bodied passenger kicked a 73-year-old woman across the width of the carriage. The septuagenarian had berated and hit the young commuter with her bag for sitting in a priority seat, despite regular seats being available. A video of the incident went viral online. Altercations over the yielding of MRT seats are not common, but they are
