The conventional wisdom that Hillary has an edge here, I think, is nonsense.
Since Chris Dodd said on national television that Hillary had electability problems, it's been fairly plain that the party seniors, at least, had made a decision / assessment that Obama is best for the party, at this time. The rest is noise.
What it means is that all the insistence on elected delegates being determinative is probably ... wasted nervous energy.
Meanwhile, there is no good resolution for the Florida and Michigan mess that is workable. With 20/20 hindsight, refusing the delegates seems to have been a poorly designed solution. Who's responsible for this mess?
