In campaign news, the billionaire casino mogul Sheldon Adelson has given $5 million to a pro-Gingrich super PAC called Winning Our Future. While individual donors are barred from giving more than $2,500 to a candidate, they can give unlimited money to independent groups known as super PACs. Adelson had previously given more than $7 million to Gingrich’s former PAC, American Solutions for Winning the Future. Adelson is the owner of Israel’s largest daily newspaper and a close friend of Israeli Prime Minister Benjamin Netanyahu. He is worth more than $21 billion.
