I suggest that you do a little research and find out just what is required of the majority and the minority in a real filibuster.
Well if you know...why not share it with us? I've heard several different things and am not sure which is true. I know the majority has a bit tougher time of it because they need to keep one more person there than the minority has. But I'm not 100% sure of how the filibuster has changed (as lamantaz has stated).
