Supporters of U.S. Republican presidential candidate Mitt Romney hold signs outside the Massachusetts State House before a news conference held by U.S. President Barack Obama's campaign's senior strategist David Axelrod in Boston, Massachusetts May 31, 2012. Obama's campaign attacked Republican rival Romney on Thursday for failing to create jobs as Massachusetts governor, calling it more evidence of a flawed economic approach that would be disastrous in the White House.
