According to NBC News, yes.
Not my first pick of the names floated this time, but, then, I want W.O. Douglas back. Kagan's record to date is left of center, but cautious. (More detail here). Still, she's young--just fifty--a consensus-builder, and a legal craftsperson of high skill. She could develop--Douglas himself was known predominantly as a corporate law professor in 1939, when he was appointed to the Supreme Court.
More, I am certain, to come.
Edited: A typo resulted in my moving Douglas to Julian of Norwich's time frame. I blame the Doctor. Or the Master. Or Adric--yeah--Adric.
