As First Family, every single thing they do is watched and remarked on. Melania deals with this better than the average woman, since she was a model. She’s somewhat used to being stared at and constantly judged. Mike Pence’ wife Karen may be having a different time, but I rarely ever see her in a public setting. This is probably the way the Pence’s want it.
That’s a good point. Melania doesn’t strike me as an attention seeker but she has the perfect background for dealing gracefully with all the cameras pointed at her. She has that ingrained “camera awareness” and poise.
