Good news for us.
What is good news for us, is bad news for Bill. Now he has to live with her for 2 more years. The divorce will have to wait.
He doesn't live with her now. There's no reason for them to get divorced because they're each getting what they want out of their arrangement. It's a business-political partnership, and he's free to pursue other "interests" as is she, so they're probably both happy. All they need do is appear in public together once a month or so. That's less than Joan Kennedy did for Ted during his abortive run at the Democratic nomination in 1980.
