Ralph Nader, the consumer activist, announced yesterday that his hat is officially in the ring as a independent candidate for president in November (it's a hat that spends a lot of time in the ring.) Neither major party, he said, is representing the American people, and he argues that he can fill that void. Tom Regan, our news blogger, has been trying to gauge reaction to the announcement today. And we're going to talk with candidate Nader, and give you a chance to talk with him. We've spoken with several of the major party presidential hopefuls in recent months, and have invitations in to the remaining candidates. Today, it's your chance to ask one third-party candidate what he stands for, and what he hopes to bring to the race.
