The billionaire casino mogul and right-wing donor Sheldon Adelson has thrown his financial support behind Republican front-runner Mitt Romney. Adelson and his wife have donated $10 million to the pro-Romney super PAC, Restore Our Future, in the past few days. Adelson initially supported Newt Gingrich during the Republican primary, giving a pro-Gingrich super PAC more than $20 million. His support prompted Gingrich to adopt an even harsher anti-Palestinian stance, declaring Palestinians are an invented people. Adelson has said he could wind up spending around $100 million to support Republican candidates in the 2012 race. He’s already spent around $35 million.
