t the Democratic National Convention Tuesday, San Antonio mayor and rising Latino star Julian Castro ripped Mitt Romney as a son of privilege who can't relate to average working Americans. The 37-year-old lawmaker, who delivered the keynote address, recalled how Romney recently said young people who wanted to start their own business should borrow money from their parents if they have to. "Some people are lucky enough to borrow money from their parents, but that shouldn't determine whether you can pursue your dreams," said Castro. "Not in American, not here, not in the 21st century. I don't think Governor Romney meant any harm. I think he's a good guy. He just has no idea how good he's had it." Romney, Castro continued,  is "perfectly comfortable" with an America in which "some folks won't even get a chance."
