I remember liking Ralph Nader back when he stood for consumer rights.
I no longer like him.
Obama said it best: "My sense is that Mr. Nader is somebody who, if you don't listen and adopt all of his policies, thinks you're not substantive".
Nader believes that he and his position are worth risking having another Republican in the White House again. I believe he must be either a huge megalomaniac or a stealth Republican.
