Your argument rests on the assumption that all other things are equal.
It doesn't. I explicitly pointed out the difference, and then mused as to whether or not, in the possibly near future, the Democrats are really willing to live with the precedent they've just set. The things that are equal are the arguments each side is making about the necessity and righteousness of their cause in 2005 and now. Cover up the names and party affiliations, and you wouldn't even know who's who. Despite the differences in circumstance, and due to that heavy helping of opportunistic language, I'm not sure if the ends justify the means.
What will they undo? These rule changes or the remaining elements of the filibuster?
They will undo whatever the Democrats do, and we might get stuck in a yo-yo cycle of doing and undoing or eventually a long stretch of one-party dominance. Some might like that. Some might also like how it'll be easier to undo things (if this eventually applies to legislation too), since traditionally it's been easier to pass things than to repeal them.
The Republicans will get rid of the remaining elements of the filibuster if and when they retake the majority, that much is obvious (look at the statements made by McConnell) there was also a chance they were going to do it regardless if Reid did this or not. So why not get rid of some of it now and get some tangible benefits from it?
You don't know if they would have. They had the chance once and didn't go through with it. The Gang of 14 is pretty much dead. By doing it themselves, they remove any criticism from the Republicans if they do it too. There was always some doubt as to whether the Republicans would do such a thing, but now that the Democrats did it first, it's more a matter of "when", and not "if".
I'm also not sure just how much tangible benefit this will have in the short term, but we'll see.
The Senate has operated by majority rule for most of its life. If a party is elected to a majority of a chamber they should be able to enact their agenda as easily as possible. This makes it easier for voters to evaluate their performance and reward or punish a certain party. It's how a lot of other countries operate
That's more like the House. The Senate isn't supposed to be like that, for better or worse.
For Joseph Biden, the Delaware Democrat and a senator since 1973, the Senate remains a place where you can always slow things down and make sure that a minority gets a voice, he said recently. And, he added, the chance to filibusterusing extended debate in order to block legislationis what makes the difference between this body and the other one.
The system of checks and balances works better when each component has unique qualities to it. Not much point if they are more alike than they are different. I feel this is generally true, even through temporary bumps in the political road, like the current Republican obstructionism.
How can it get worse? We're already seeing virtually no cooperation: ENDA and immigration reform won't pass the House, Congress can't put together a yearly budget, and rarely anything comes out of the Senate anyway. How would leaving the filibuster intact solve anything?
His point about removing minority rights and debate for future sessions is pertinent. "How can it get worse?" is a silly question. Things can always get "worse". Leaving the filibuster intact isn't necessarily about solving anything, but rather more about preserving an institutional process that exists for a particular purpose. If you are looking at the situation from the point of view of the Democratic constituency, then of course it's in their best interests, and the end would justify the means. Of course, there are still the other 50% of the country that do have a say in the matter, too.
Americans don't care about the rules of the Senate they care about results.
Most Americans don't care about politics in general outside of major elections. The ones that do, mostly care about their own team's agenda.
I don't get it. Are you arguing just to argue?
