Just not for Court nominees, who deserve an up or down vote, according to long-standing Senate Rules.
I seriously doubt if a fillibuster happens.
Both political parties, for different reasons, want this bill enacted into law.
This is the reason that they negotated in secret. They knew it would create a firestorm and did not want it publicized until the last second. They hope that it will be passed before serious opposition can be organized against it.
Time is not on our side on this one.
