Indeed, we should rein in this obnoxious abuse. As you write, "Senators who want to mount a filibuster should have just one chance of doing so" — preferably only once in six years, in my opinion.
As Thomas Mann and Norman Ornstein make clear in their book, "It's Even Worse Than It Looks," today's senators use the filibuster infinitely more often than their predecessors did. Worse yet, they have added the shameful custom of the "hold," by which a single senator can secretly stop any legislation or nomination from being debated or coming to a vote.
Let's get rid of these abuses, which darken the reputation of what once was a showcase of American democracy.

The suggested reforms to the filibuster rule don't go far enough. Sixty votes to end a filibuster is an impossible hurdle, and 40 to sustain one is too easy.
