OK, now that I have your attention :-)
The Edwards endorsement is fantastic. It creates momentum heading into the final stretch. It switches the subject from a week of "Obama can't win white, blue collar, lower income, older voters." It effectively adds 18 delegates to Obama's total even if the mechanics are such that the various counting services might not be able to add them in. With the 18 plus 4-5 supers a day plus at least half of the OR/KY total Obama may just pass 2025 next Tuesday night. But there is one new meme that will come out of this, one new talking point the Clinton team will use for a week.
