President Obama today defended his comment that Washington can only be changed "from the outside," and mocked Mitt Romney for trying to turn it into a political issue. "For some reason, my opponent got real excited," Obama told backers in Woodbridge, Va., before firing back at Romney for saying he could get the job "from the inside." "What kind of inside job is he talking about?" Obama said of Romney. "If it's rubber-stamping the top-down agenda of this GOP Congress, we don't want it."
