The filibuster doesn’t need to be eliminated. It can serve it’s purpose if we hold to the original implementation: Make members read the phone book on the floor on Sunday morning at 2am instead of requiring 60 votes to end debate.

Filibuster is almost never used. It's occasionally threatened, frequently used as an excuse for not even trying, but rarely used. If it were used more often, it would elevate the debate around the bills under consideration. Congress doesn't even try.

The threat of a filibuster is enough to make it not worthwhile to bring legislation to the floor. "debate" is pointless when everyone's mind is made up.
