My understanding of the filibuster is that it is essentially unlimited debate on a bill. A Senator (or series of Senators) can get the floor an talk until they drop. It has been termed "talking a bill to death".
It seem that the system is now that a Senator can declare a filibuster, but not actually have to do the talking part. Unless the bulk of the Senate votes to terminate debate, it seems an individual Senator can kill a bill. One thought is, yes you can do a filibuster, but you have to do the talking part.
