Update; no decision this week. Probably wise as tomorrow is the anniversary of the White Night Riots that erupted after the verdict against Dan White. The 22nd is Harvey Milk's Birthday. That would not have been an auspicious day for this. At least one blogger reports that someone figured this out and scuppered the announcement at the last minute because of the date. Another says that the someone was SF Mayor Gavin Newsom, though that's been discounted.
More discussion at my DailyKos diary, since no one comments over here!
Keep an eye out Friday to see if they will announce for Tuesday next week.
