I've got a theory about the Edwards candidacy, but it's very much politically IN-correct, so I don't know if I should blurt it out for fear of invoking the wrath of the Admin Moderator.
But within the realm of socially acceptable discourse, if Edwards could win Iowa, and then somehow build on that to win South Carolina, then he would definitely have some momentum.
He is way behind in South Carolina. I don’t see how he could win that.
