WHO'S NEXT? Kevin Drum pointedly asks the right (and wry) question about The Times' data-driven reporting on power couples: "Who's next?"

I'd like to see some data on President and Laura Bush, for one, and how many weekends they spent together over the past year, despite living in the same house and same city. Maybe then we can move on to Sen. Chuck Schumer, who lives on Capitol Hill with a group of other congressmen, returning to see his wife and kids in New York on weekends. Or maybe a better point of comparison would be Sen. John McCain, since his website says, "He and his wife, Cindy, reside in Phoenix." How often does he get out there to see her, again? And how often does she visit him in Washington?
