E.J. Dionne proposes an alliance of public-spirited citizens to offset big super PAC spenders and destroy incentives for the very rich to buy the election. But could there ever be an alliance spirited enough to discourage a buyer like Sheldon Adelson?Adelson on Wednesday gave $10 million to the pro-Romney Super PAC Restoring Our Future. But Forbes reports the casino billionaire is now so intent on seeing Barack Obama defeated that further donations might be limitless. Thats presumably more than the $100 million he was willing to part with to put Newt Gingrich in the White House, and its all to keep the country from turning any more socialist than it already has in the past three-plus years.Socialism, or what some decry as redistribution of wealth, has clearly been good for Adelson. Forbes own figures show that since Obama took office, Adelson has made more money than just about any American.
