The Senate is voting on whether to limit debate and amendments to the financial reform bill right now. Go watch the roll call with the Sunlight Foundation folks, who are annotating the vote with info about campaign contributions and personal asset statements, and offering handy explainer chats for those not in the habit of watching CSPAN for fun.
UPDATE: 57 votes for cloture. Motion fails. The debate continues.
UPDATE 2: Nope. They're voting again!
UPDATE 3: Nope again. More yammering and then a quorum call.
