Edwards' message was a "have/have nots" diatribe.
I'm really certain that this year the pubbies need to demonstrate that the "haves" are the rich dems and their incredibly powerful and rich supporters.
That's what I remember most about Edwards - that disgusting "common folks vs. the Evil Rich" stump speech. Absolute pandering to the stupid. I'll bet the reasoning behind Lurch's decision was simply that Edwards is young and pretty, and X amount of Stupid Females are going to vote for him because... well, he's young and pretty... with the race so close, he doesn't need much to get him over the winning line, and he might have just felt this is it.
Personally, I would rather have seen Gephardt, just in case... I can't believe anyone could seriously make a case that Edwards is in any way qualified to run the country.
