I like the ideas that both of you have displayed. The term 'nuclear option' is really one that is meant to ellicit harsh reactions and I don't think that it should be allowed to define the debate. It is also wrong, as in the 'quagmire', 'Vietnam repeat', 'massive civilian casulties' vein.
My next question is: What if Bush made recess appts., do they have to exit as soon as Congress reconvenes? Or does a replacement have to be voted on? Will they filibuster that or be glad of the replacement? Does the recess appt. stay until a new judge has been voted on? Depending on the answers, it could be a new source of hardball. It would go well with your suggestions.
Recess appointments of life-tenured judges are uncommon. Clinton did it on his way out the door, and so did Carter.
