The Dems just changed the rules so that if the Reps take the WH and have a single member majority in the Senate then they could appoint Sarah Pallin to head the Dept of Education. That is fucking scary. How about judges? Usually neither side can get judges that lean wildly to their side and usually have to settle with judges that slightly/moderately lean their way, now it only requires 51 votes for them to appoint uber right wing judges (or left wing, doesn't matter).
I agree that there hasn't been a whole lot of compromise going on in politics these days but despite its recent overuse the filibuster has been sort of a checks and balance that keep the ruling party from radically shifting government by appointing people at the fringe of their party instead of people that are more moderate.
Bottom line is, the Dems did it to stop the Reps from blocking what the Dems want to do. When the Reps regain power, and they will eventually (perhaps next election), they will be able to use the exact same rule to do the exact same thing. There is a reason why the rule has survived until now, now precedent has been set and both parties get to use it.
Hell, your side won't even be able to get "payback" on the Reps when/if they regain power. Instead the Reps will have precedent to not only abuse the rule just passed but to pass worse rules that will basically invalidate the minority party. That is just a bad fucking idea regardless of which side is in power.
Except the Dems just willfully and purposely removed the one safeguard they had to prevent them from doing batshit crazy stuff. Again, bad idea.
