What made the friendship between Scalia and Ginsburg work

The question comes every time. “Excuse me, but there’s something I don’t understand about Justice Ruth Bader Ginsburg,” someone will ask my co-author and me at each event since we published “Notorious RBG,” a lighthearted biography of the justice. “How could she possibly be friends with Scalia?”
Now that Senate Republicans have vowed, mere hours after the death of Justice Antonin Scalia, to block any Obama nominee to replace him, it’s worth considering the answer.
Nino and RBG, the court’s most famous odd couple friendship, the subject of the recent comic opera “Scalia/Ginsburg,” stood as an example of warmth and professionalism across traditional divides. For Ginsburg, who has been outnumbered throughout her career, it was also about making the institution work, no matter their disagreements. WashingtonPost.com
