Well perhaps but some is a but unavoidable.
Kagan and Sotomayor are new. We just have very little to go on for them.
That makes it unfair to the rest as people won’t likely pick them since there is no data.
But that is just how it is and worked out. I could have waited 5 years to ask the question so we had some basis for them but pretty sure I’d forget to ask it (can’t remember what I had for lunch). In five years there might me three more new justices…or none. No telling.
Alito and Roberts are not a whole lot better. Relative noobs as SCOTUS justices go.
That leaves us with Breyer, Ginsburg, Kennedy, Scalia and Thomas with any real resume to sort through.
Being a liberal board not hard to think the hammer will fall on Scalia and Thomas (I am surprised at the votes for Roberts but I guess, seeing this, it makes strategic sense). Frankly I can make good cases for magicking them off the island.
I can only guess you picked “no one” because Obama gets to replace the justice. Personally, given the OP and if I were conservative, I’d toss Ginsburg since Obama has been appointing people arguably more conservative than she is. Get rid of the last true liberal on the court.
