Who Is Sheldon Adelson and Is He behind Gingrich's Rise? After Newt Gingrich 's big win in South Carolina , polls showed him neck and neck with Mitt Romney in Florida. Commentators agree that Romney was the aggressor in last night's debate and Gingrich almost passive compared to past performances. If Romney can win Florida, establishment Republicans will be very relieved. But Gingrich supporters will air a blitz of TV-commercials before Tuesday's primary. It's financed by Las Vegas casino magnate Sheldon Adelson , who's contributed $10 million to Gingrich's Super PAC. Has last night's debate role-reversal made a difference? Who is Sheldon Adelson, and is he making Republicans more hawkish in defense of Israel?

Is the threat from Russia missing from the Russia meddling probe? There's much being made about the Trump administration's possible ties with Russia. But the bottom line is Russia's effort to influence American democracy. Do the President and his aides care enough to take action before voters go back to the polls?
