So, 4:00 came and went. Oh well. To keep you busy until The Moment happens (unlikely today, but who knows?) Mark Halperin has an updated CW on the choices:

Obama

1. Joe Biden
2. Chet Edwards
3. Evan Bayh
4. mystery person
5. Jack Reed

McCain

1. Mitt Romney
2. Tim Pawlenty
3. mystery person

I had excluded Chet Edwards from my own list yesterday -- hey, none of these lists are definitive -- but who am I to blow against the wind? Rep. Edwards, you're in the first tier!
