After bankrolling the main super PAC supporting former House Speaker Newt Gingrich's failed presidential bid, Sheldon Adelson pivoted to support GOP presidential nominee Mitt Romney and his primary super PAC. Adelson has also reportedly funneled tens of millions more to conservative 501(c)(4) nonprofits, according to the Huffington Post . These groups are not required to disclose their donors.
Among them are Crossroads GPS , the Young Guns Network and groups aligned with the Koch brothers, the story said, citing unnamed sources.
All told, including donations given to both super PACs and nonprofits, Adelson and wife, Miriam, contributed more than $150 million to pro-Republican efforts during the 2012 election cycle, according the Huffington Post . Giving to super PACs alone, exceeded $93 million, which is more than any other individual or married couple.
At first, the casino magnate and top donor to super PACs was best known as a Gingrich’s most generous supporter. Adelson’s wife, Miriam, a physician, even wrote a $5 million check to the pro-Gingrich super PAC Winning Our Future in late March. Days later, Adelson admitted that Gingrich was “at the end of his line.” The $5 million contribution was later refunded.
Until that point, Gingrich, who suspended his campaign on May 2, 2012, was the sole beneficiary of Adelson’s largesse. By Election Day, scores of candidates were aided by super PACs at the receiving end of Adelson's political contributions.
Gingrich and the Adelsons have known each other for years, and share similar pro-Israel and hard-line views on the Middle East. The Adelsons have donated hundreds of millions of dollars to various Jewish and Israeli causes through several charitable foundations they have created. Sheldon Adelson, born in 1933, is of Jewish-Ukrainian descent, and Miriam Adelson has dual citizenship in the United States and her native Israel.
Roughly two-thirds of Adelson’s $93 million went to super PACs that backed just one or two specific candidates. None of Adelson’s preferred candidates prevailed in any of the 10 races in which these super PACs were active.
Adelson was born in Dorchester, Mass., and attended City College of New York for some time before dropping out. Before entering the casino and gaming industry, Adelson worked as a mortgage broker, investment adviser and financial consultant. His biggest early business success was the annual Comdex computer trade show, which he and his partners first organized in 1979 and sold for $862 million in 1995.
Though Adelson lost heavily in the Great Recession, shares of the Las Vegas Sands Corp. have climbed from 2008 lows of less than $2 to more than $52 in early 2013, and Forbes reports he is the nation's eighth wealthiest man worth an estimated $21.5 billion. His casino empire extends across the United States and Asia, and the company’s annual report shows more than $9.4 billion in revenues in 2011.
The Las Vegas Sands Corp. has been under investigation by the Securities and Exchange Commission and the Department of Justice for more than a year on possible charges of bribing foreign officials, and more recently, for possible money laundering. A former executive’s 2010 wrongful-termination lawsuit also alleges that Las Vegas Sands Corp. was involved with Chinese organized crime groups.
Sen. John McCain, R-Ariz., a longtime campaign finance reform advocate, said the corporation’s activity abroad raises foreign money concerns.
“Obviously, maybe in a roundabout way, foreign money is coming into an American campaign,” McCain said in an interview  with PBS.
After Obama was re-elected on Nov. 6, the Hebrew-language newspaper owned by Adelson in Israel ran the news with the headline  “America Chose Socialism,” according to Business Insider.
