Is it time to get rid of the filibuster?

The framers of the constitution envisioned a Congress in which it takes a simple majority to pass legislation. The House conforms to the constitution in this respect, but the Senate allows any senator to invoke a filibuster, essentially stopping progress on any given bill until 60 votes can be obtained.

There used to be a cost in doing so, since the senators would have to hold up the business of the whole Senate as they read chicken soup recipes into the Congressional Record, making themselves either very popular or unpopular depending on the cause. But now, there is absolutely no political cost to invoking a filibuster. Any anonymous senator can file a motion to set the bill aside and the business of the Senate marches on.

In the present Congress, the Republicans are invoking a filibuster on every piece of legislation; in effect, requiring a supermajority on every vote. All it would take is 51 votes to end this this practice, and unblock the logjam of legislation that has been created. Do you think we ought to do this?

As you can see from this chart the filibuster is being invoked at twice the rate as has historically been the norm.
