Unless the Senate rules require a supermajority to amend (and they might--I don't know), then the Republicans should simply vote that filibusters do not apply to nominations.
Talent's scenario would work also.
Whats scary, is that you seem to be one of the very few people who understand this, thats my opinion after having been reading about this for awhile. Its not even a law, its a senate rule, why is it so hard for people to understand that?
