Ralph Nader's once sterling legacy gets tarnished again -- by Ralph Nader. This time in an attempt to get some needed attention he takes shots at Obama.

Just how different is Obama from John Edwards? I continue to believe that Obama will select Edwards as his running mate, yet recall that Ralph Nader endorsed Edwards this year. Does Ralph honestly believe there is a chasm between his choice, Edwards, and Obama? If so, he definitely has a bolt or two loose, but me thinks it's simply more so vanity and publicity-seeking mouthing off. Sad.
