New count for Feb. 5th states: Hillary 971, Obama 709.I think Hillary wins for every day Edwards doesn't endorse Obama, and in the long run Edwards being out hurts Obama. However, with Edwards out Obama gets the vast majority of delegates in his home state of Illinois, which gives him a boost from my previous guesstimate.
Also, new polls in Oklahoma shows Clinton weakening, and in California Obama's gaining ground faster than Clinton. Hillary's still well ahead in both states, though; in Oklahoma Obama was third before Edwards dropped out today...
