He’s already given at least $20 million to Newt Gingrich’s failed campaign, but now right wing billionaire Sheldon Adelson is poised to donate as much as $100 million to Mitt Romney, in what can only be described as a blatant attempt to buy an election.

Forbes has confirmed that billionaire Sheldon Adelson, along with his wife Miriam, has donated $10 million to the leading Super PAC supporting presumptive Republican presidential nominee Mitt Romney–and that’s just the tip of the iceberg. A well-placed source in the Adelson camp with direct knowledge of the casino billionaire’s thinking says that further donations will be “limitless.”

Adelson, who has built Las Vegas Sands into an global casino empire, will do “whatever it takes” to defeat Obama, this source says. And given that Adelson is worth $24.9  billion–and told Forbes in a recent rare interview about his political giving that he had been willing to donate as much as $100 million to his initial presidential preference, Newt Gingrich–that “limitless” description telegraphs potential nine-digit support of Romney.

Adelson has said he might spend as much as $100 million on this election. That’s about one-half of 1 percent of his wealth.

Put another way, if the typical American family gave the same percentage of its net worth, the family would write a check for $360.
