A letter written by a staffer for Lyndon Johnson just after his victory in 1964 explains what the filibuster was like in former times and what it is today. And, to my surprse and embarrassment, I never appreciated this huge difference, despite a lot of time spent getting a graduate degree in politics from a very fine university.
I found out that the filibuster is today a tool for a supermajority for almost anything that matters rather than an temporary halt in the Senate's business to try and slow the majority down and arouse the energy and attention of the nation..
In other words the filibuster was used in the past to try and halt a vote but not to actually prevent it from ever happening. But today, with a radicalized Republican party and a Democratic Party asleep at the switch, the filibuster is now used to make anything and everything pass a 60 vote hurdle.
Here is the article by Ezra Klein in the Washington Post relating the analysis by a staffer under LBJ. The staffer was Mike Manatos and he served as White House liaison to the Senate. The really interesting part was the vote for Medicare, which was, initially, 55-45. The vote swelled to over 65 when it was apparent it was going to pass because the Republican Party, in those days, was not a party determined to defeat a president and discredit an entire opposition party at any costs.
That was then, and now is now. Surely, we can change this, in 2010, when the new Senate is organized.
