"If a bare majority can change the fundamental rules that govern an institution, then there are no rules. Senate rules today are whatever the majority decides they are that morning. What distinguishes an institution from a flash mob is that its rules endure. They can be changed, of course. But only by significant supermajorities. That’s why constitutional changes require two-thirds of both houses plus three-quarters of the states. If we could make constitutional changes by majority vote, there would be no Constitution. As of today, the Senate effectively has no rules. Congratulations, Harry Reid. Finally, something you will be remembered for."

“Courage is not a quality one normally associates with mathematicians. Yet it should apply to people who work in their attics in secret for seven years without cease on a problem that has eluded the greatest mathematical minds since first proposed in 1637.”

“Affluent enviros are all for wind farms, until one is proposed that might mar the serenity of a sail from the crew-necked precincts near Nantucket Sound. Then it's clean energy for thee, not for me.”

“In explaining any puzzling Washington phenomenon, always choose stupidity over conspiracy, incompetence over cunning. Anything else gives them too much credit.”
