The above calculation doesn't count the 19 delegates whom John Edwards has encouraged to back Obama, or the delegates pledged to Clinton who have begun flipping for Obama. It also doesn't count the super delegates, with whom Obama holds a substantial lead, but who I do not believe should have any say in a democratic election.
You know who should have a say? Active citizens, including citizens who speak up for others at home and abroad, including the peace movement, the labor rights movement, and all of those whom Clinton effectively credited with her defeat back in April. She was speaking specifically about her losses in caucuses, when she disdainfully referred to us as "the activist base of the Democratic Party." According to Clinton, these activists "turn out in great numbers. And they are very driven by their view of [my] positions, and it's primarily national security and foreign policy that drives them. I don't agree with them. They know I don't agree with them."
You're damn right, and we defeated you, and we'd like you to leave now. We've had more than enough. Get out of the "race" now! Got an exit strategy? Use it.
