Leslie Stahl’s face evinces shock as Arnold Schwarzenegger talks about cheating on his wife, Maria Kennedy Shriver, on a CBS “60 Minutes” interview. The former bodybuilder and California governor was sorry that “I inflicted tremendous pain on Maria” – but obviously not very. There was no show of like or dislike for the wife, but the most infuriating response of all – indifference.

Maria knew Arnold was fooling around when they were still “dating.” His marital infidelities, including the tryst with the cleaning woman, are Hollywood commonplaces. And so why would sophisticated people make such a big deal out of Arnold’s doing what his outsized persona was wired to do, which is ... whatever he wanted?

The reason is that Maria Shriver is a Kennedy princess. She was not one of those starlet nobodies who claimed during his campaign for governor that Arnold had groped them. Indeed, Maria indignantly attacked their credibility.
