The History of the Filibuster
Sarah A. Binder, April 22, 2010

“Short-term, pragmatic considerations almost always shape contests over reform of Senate rules.”

On the one hand, I hate learning that I’ve held a mistaken notion for so long.  On the other hand, I love it because unlearning requires opening the floodgates to a new perception.  Unfortunately, I’m still stuck with the suspicion that, regardless of the party in the minority, those short-term pragmatic considerations mentioned by Dr. Binder are going to continue to hold sway.
