Wow, this is really coming down to the wire. I just read an article which mentioned Obama is doing very well in the bay area and nearly all the Democratic Representatives there have endorsed him. It also had several Pelosi quotes that implied she is very much in favor of Obama even if she won't come out and say it.
"Nearly All" as in 3 out of 11?
Obama has 3 (Miller, Lee, and Lofgren), Clinton has 3 (Woolsey, Tauscher, and Lantos), and the remaning 5 are uncommitted (Pelosi, McNerney, Stark, Eshoo, and Honda).
Now, it's possible that those uncommitted will break for Obama over the next couple days, but he doesn't have them yet.
