Sorry, no link yet, but the Senate is debating at the moment after an amendment was added last night at midnight, on a 49-48 vote, to limit a guest worker provision to five years, after which it will have to be renewed. Republicans have gone ballistic, because big business considers this the main point of the bill. They have said that if the amendment remains, they will vote against the bill. If they do, Reid has said he will pull it from the floor, effectively killing it. Much arm-twisting going on right now, but it looks like it's dead unless Bush and the Republicans blink.
