When the citizens of a great republic elect their president, the future first lady is part of the packaged deal, at no extra cost... particularly if the president himself has lots of wealthy friends with jet planes, luxury yachts and Mediterranean mansions. Normally, voters can't complain if they were to discover that the first lady likes to be photographed in all kinds of interesting situations.
In France today, there's a minor irregularity in the sense that voters had no idea that the president they were electing would be switching first ladies during his first six months in office. So, a disgruntled citizen might grumble bitterly: "We thought we would be getting lady X, and now you're forcing us to accept lady Y." But, as I said, only a miserly voter would lodge such a complaint, because the nation gets the first lady for free (in theory), as part of the global bargain.
There's another approach to this question. Few people would feel like leaving their children in the care of a couple who've never succeeded in keeping their own kids off the street. How should we feel about confiding an entire nation to a guy who apparently can't keep his female off the front covers? And a female who can't keep her clothes on?
