What I'm happiest about is that the mainstream of Senate reform discussion seems now, much more than it was a few yeas ago, to recognize that there are differences between the filibuster on legislation, on judicial nominations, and on executive branch nominations. Moreover, whether by design or not, we've wound up with some recognition that exec branch nomination filibusters are at least highly problematic.
I am disappointed that supermajority confirmation for exec branch nominations survived. I continue to believe that simple majority cloture is the way to go for exec branch picks. It's possible that we'll now have that de facto; we'll have to see. I'd rather hve it by rule.
On the other hand, for those of us who want a middle ground -- filibuster reform, rather than a majority party rule Senate -- it's good news that we did not get majority-imposed reform. It's of course hard to tell exactly how much it matters, but I do think that one successful "nuclear" blast will make a House-like Senate quite a bit more likely.
Of course, all this is pending how things actually work out in practice. We'll know more in a few months.
