Someone up thread referred to the filibuster as a "gentleman's agreement". It's a good way to describe it, and a good way to sum up why we're here at this point as well. There's a lot less "gentlemanly" treatment between the parties.
And ultimately, both parties have had their hand in it. The two largest examples of what's got us here in this particular instance is the Republicans refusing to even allow Garland to make it to committee, while on the flip side you had the Democrats already previously using the "nuclear option" on every court appointment below SCOTUS level.
Actions, ultimately, have consequences and politicians seemingly have long memories when they've been slighted. Indeed, both of those instances were themselves justified by pointing to things in the past where the opposite side threatened or did similar actions.
Generally, we'd all like to see someone stand up and act like an adult and end the cycle; however, not surprisingly, it always seems to be people wanting the other side to be the first one to act in that fashion
I've stated my feeling previously. I think Garland should've been brought to committee and given a hearing. As it relates to right now, I'm not a huge fan of the nuclear option. However, if it is to be used, it should be done in this fashion:
Institute it. Use it in this SINGLE instance. Indicate
clearly that this is a consequence of Harry Reid instituting the Nuclear Option previously for all other court appointments, and that it is a lesson that opening Pandora's box WILL have consequences. You then IMMEDIETELY re-instate the filibuster rules not just for SCOTUS but for LOWER COURTS as well; completely dismantle the Harry Reid rules. And, whether or not it hampers you the rest of Trumps term, you leave the old filibuster rules in place. You make it abundantly clear that the use of the nuclear option was ONLY "blowback" from Harry Reid's previous action and a warning against doing such a thing again in the future, while at the same time showing that you are going to set things "right" and that you'll deal with the hassle doing it the "right" way will cause you.
It'd make things in the future harder for the Republicans, but would go a long way in returning things a back to the old order...while at the same time not incentivizing the Democrats to use the nuclear option again in the future expecting Republicans to just roll over, take it, and get rid of it once they're in power.
