With more than $20 million in donations, Sheldon Adelson almost single-handedly bankrolled Newt Gingrich’s presidential campaign this year. The staunch pro-Israel hawk, who opposes any land concessions to the Palestinians, has since hopped on board the Romney money train and gotten behind a high-profile effort to convince Jewish voters to vote Republican, even traveling on the candidate’s recent trip to Israel. Not one to mince words, at a recent major fundraiser Adelson reportedly referred to the president as a “crybaby” who should be in diapers. The Las Vegas mogul has also attracted some unwanted attention with his controversial casino interests in Macau, including a federal investigation into allegations that his employees made illegal payments to Chinese officials. Adelson has pledged up to $100 million to the effort to defeat Obama, which should be more than enough incentive for the Romney campaign to keep him happy.
