Class and gracefulness are not two adjectives I’d use for MObama
I believe Jackie was also fairly quiet and not real “political”, except to back up her husband on his politics. And when she died, I remember commentators stating that most Americans rarely heard her speak.
Contrast that to Mrs. Obama, out complaining about her lot in life, race relations, George Bush, that state of our country, whatever. Other than the pearls and maybe the hair, I see no similarities at all.
