Supporters of U.S. Republican presidential candidate Romney boo as U.S. President Obama
Supporters of U.S. Republican presidential candidate Mitt Romney boo U.S. President Barack Obama's campaign's senior strategist David Axelrod as he speaks during a news conference outside the Massachusetts State House 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.
