Tribe didn’t write the article, but he’s 72 and no one would consider appointing him or anyone else at that age. The idea is to find someone 50ish who will (hopefully) be around a long, long time.
If the kenyan gets another appointment it would not surprise me to see an appointee in the 40 Y.O range, or less. History shows that young Conservative appointees often tend to become flaming leftists on the Court. Younger Libs just lean farther left. Watch the obamacare cases coming up. We may see that the kenyan doesn’t need another appointment. Roberts just might continue in the direction he showed the last time with obamacare.
