Drudge Report has a red banner headline that a Federal judge will issue his ruling at 6 PM Pacific time today on the constitutionality of Proposition 8, which prevents gays and lesbians from being legally married in California.
I apologize for the lack of links, but other than the non-hyperlinked headline on Drudge, there aren't any links (yet). Neither the San Francisco Chronicle nor the Sacramento Bee (which has a section on its website dedicated to Proposition 8 coverage) is reporting any activity.
I'm loath to trust Drudge - particularly when he doesn't link to any story - but given the Massachusetts ruling today, this would be an amazing event.
