U.S. President Barack Obama's campaign's senior strategist David Axelrod (C) stops to shake a protester's hand as he leaves a news conference at the Massachusetts State House in Boston, Massachusetts May 31, 2012. Obama's campaign attacked Republican rival Mitt 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.
