The Senate has gone nuclear. My first notes are up, over at Plum Line.
I'm sure I'll have more on this, but one quick note. Soon after the key vote, Harry Reid asked for, and received, unanimous consent for committees to meet. That's normally a routine request. The fact that it remains a routine request, even immediately after the Democrats acted, is a quick answer to one question: no, Republicans will not "blow up" the Senate to retaliate for majority-imposed reform. I suppose it's possible that they'll regroup and change their minds, but much more likely will be some sort of minor "blow up" demonstration, nothing more. McConnell didn't really even make a lot of threats about it, at least not today.
OK, my prediction of a GOP surrender (well, I made odds on it, so not exactly a prediction) didn't work out so well, but this is one that it looks like I was right.
I'll also say that I don't really believe that today's action is going to matter at all in terms of bipartisan bargaining in the future. We'll see; a lot of smart observers think it will, plus I'm hearing Wolf Blitzer just now talking about "poisonous atmosphere." We'll see, but I really don't think that the "atmosphere" stuff is really going to make any difference at all.
