You can't fight a definition that exists only the minds of the individual members of the Dirty 14. If the constitutional option (aka the Byrd option BTW) is tried again, the same 14, probably joined by a few others, will just agree to subvert the will of the majority, again, encouraged by their success in doing so this time.
You may very well be right, alot depends on the behind the scenes stuff. As long we have the majority it will still push our way, slowly maybe but still our way. Rome wasn't built in a day. If they want to get "an extreme" Judge to vote they just need to get the Dems to play the filibuster card a couple of times then throw up their hands and say we tried. We are then right back to where we started but with a couple of Judges already appointed.
