Charles Krauthammer gets to the heart of the matter:
The violence to constitutional norms here [with the filibuster's destruction] consisted in how that change was executed. By brute force — a near party-line vote of 52-48. This was a disgraceful violation of more than two centuries of precedent. 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.
Read it all. I doubt you’ll find a better exposition of the profound damage the Obama administration is doing to the Constitution and to America.
