Next Stop, Supreme Court?
It's likely that the next president will face at least one Supreme Court vacancy. Obama should promise Hillary Clinton, now, that if he wins in November, the vacancy will be hers, making her first on a list of one.
Obama and Clinton have wound up agreeing on nearly every major issue during the campaign; at the end of the day, they share many orthodoxies. Unless the Supreme Court were to get mired in minuscule details of what constitutes universal health care, Obama could assume that he'd be pleased with most Clinton votes, certainly on major issues such as abortion.
