I don't know but it would provide a handy list of names we should be sure to primary at the next possible moment. A little RINO plasty is in order LOLOLOLOLOLOLOLOLOLOLOLOL
Most of the Republicans that will vote for Sotomayor's confirmation are either: a) not even close to RINOs (Graham and Hatch come immediately to mind) or b) moderates that would be replaced by Democrats if they were to be primaried by a more conservative Republican (Snowe, Collins).
So explain to me how it helps your cause to primary these people. If anything it would weaken the Republicans even more. Of course, I have no problem with this, but your logic seems to be counter to what your final objective would be (which I assume is a Republican controlled Congress).
