George Soros, the Jewish billionaire investor, has announced $1.5 million in pledged donations to a trio of super PACs backing Obama and congressional Democrats

Soros, who became nationally prominent in 2004 when he spent more than $20 million on independent groups supporting Sen. John Kerry (D-Mass.), will give $1 million to Priorities USA Action — which is supporting Obama — and $500,000 to Majority PAC and House Majority PAC, which are running ads on behalf of Democratic candidates for Congress.
