LZ Granderson: Obama showed what he knows about fighting for the little guy
President Obama did not promise heaven and earth, as he did four years ago. And it's a good thing because I doubt many would have believed him. Instead tonight's speech at the Democratic National Convention served as a reminder that beyond the soaring rhetoric and heartwarming smile is a man whose entire adult life has been about fighting for the little guy. Not to win elections mind you, but because he was once a little guy himself and he comes from a hardworking, middle class - and diverse - family.
In that context he talked about the importance of establishing policies that are designed not to carry people but to lend a helping hand when needed. He emphasized education and the impetus behind health care reform.
