Like Dina McGreevey and Silda Spitzer before her, in the first episode, Margulies stands by her man during a press conference in which he denies allegations of trading political favors for financial and sexual ones. (He also has a penchant for prostitutes.) Eventually he gets locked up, and his wife has to pick up the pieces and go back to work to support her family. She's a lawyer — just like Hillary! — who goes to work at a firm run by Christine Baranski, a ball-buster who brings her lapdog to the office.
It's kind of amazing that this is such a seeming trend that it warranted an entire series. Maybe it could even work its way up to becoming a genre, like mob movies?
