I can tell you exactly where the Republicans are. They and Lott, I mean Frist, are trying to figure out how many special vacations and holidays they can allow the democrats, instead of forcing them to filibuster 24/7, taking turns sleeping on cots in Senate chambers. There is absolutely no other way Estrada will get voted on, but Republicans refuse to do this. They also refuse to put all Senate business on hold and to deny all pork to the democrats. That, in addition to forcing a full filibuster, would be a big help as well. But Senate Republicans refuse to do that, either.
In short, they are slowly surrendering to Schumer, Kennedy and all the rest.
