Maybe he became a constitutional law “expert” so he could learn how to sidestep it and dismantle it.
Saul Alinsky showed him the methods for that a long time ago.
Considering nobody remembers him from Columbia and even
though he was listed as editor of the Harvard law review he didn’t
write a SINGLE REVIEW. He almost certainly had a stand in do all
work in his name and take all his tests while worshipped at the altar
of choom. Once he had his law license...acquired for him by his
academic doppleganger an “accident” was arranged and O stepped into
his new life. Then when he had to actually use his his license his
gross deficiency’s started to show. Eventually he surrendered his
law license to avoid having to explain.
It’s as good a theory about him as any other.
