The biggest tear-jerker moment in John Edwards' speech:
When he broke from his written script to talk about one last campaign stop—a New Orleans bridge where more than 100 homeless residents sleep every night and are fed by a local pastor with money from her own pocket.
Edwards described how, en route to giving his speech, he stopped his bus, got out and moved among the people there under the bridge.
"A woman said to me 'You won't forget us, will you? Promise us you won't forget us.'"
