My sense was Edwards, Sharpton, Braun, Kucin., were in the race for dual purposes: to pay their dues in developing name recognition for future races and/or possible VP to demonstrate their ability to campaign, get some votes, and staying in to try to help the party educate the public on the issues. I saw Edwards as a natural for a future run for the Presidency, but he's making a strong showing in the polls, etc....he's a viable candidate in this race, and not just a pretty face.
Hearing Kerry speak tonight was an eye-opener--I liked what I heard, especially the phrasing on special int. groups holding hostage, the right wing going after civil liberties.....
Sharpton and Kucinich and Braun are in it for speaking fees.
