I have never doubted for one second that if the roles were reversed the Rats would have ended the filibuster in the first year of their presidents first term and then would have said "quit acting like a bunch of babies crying about it".
The senate is well within its rights to set its rules and why have a majority if your not for something. If your for something then gosh darn it get it done, or get out of the way and let somebody else get it done.
