Summary: Politico reports that Barack Obama’s aides and advisers are preparing to center the president’s reelection campaign on a ferocious personal assault on Mitt Romney’s character and business background, a strategy grounded in the early-stage expectation that the former Massachusetts governor is the likely GOP nominee.
