I was an Edwards supporter. 
The guy had a good platform, and he sounded like a real, genuine progressive. I don't doubt that if elected, he wouldn't have been anything slightly above a Palin level disaster, but I couldn't begrudge anybody for supporting him back then.
I had a friend who worked in the Edwards campaign. He's one of the smartest guys I know. He never got high enough in the campaign to witness any of the horror stories I just read about (I think), but he was practically sweating blood with his workload and that was before the Iowa debacle. I spoke to him only once before the run up to South Carolina and I don't think I've ever spoken to a more fatigued person in my entire life, he wasn't just tired, he was weary. At that point the writing was on the wall, many people had jumped ship, money was running out.
I just wanted to express my frustration at that prick Edwards. His narcissism put a lot of good people through shit just to prop up his absurd power fantasy. Its a shame that so many people spent their time and money on a John Edwards that didn't exist, and maybe never did.
