According to fundraising figures released this week, the pro-Obama super PAC Priorities USA Action raised just $4.1 million in itemized donations in 2011. The bulk of the donations came from reliably liberal donors - Hollywood and labor. In contrast, Restore our Future, supporting Republican candidate Mitt Romney, raised more than $30 million, much of it from the financial industry. Casino magnate Sheldon Adelson and his wife Miriam gave a pro-Newt Gingrich super PAC $10 million last month. The disparity may show that Obama has little need to rely on super PACS.
